Anything that has mass and takes up space
Correct Answer
A. Matter
Explanation
Matter refers to anything that has mass and takes up space. This includes both tangible objects, such as a book or a table, as well as intangible entities, such as air or light. The concept of matter encompasses all physical substances and materials in the universe. Volume, on the other hand, refers to the amount of space that matter occupies. It is a measure of the three-dimensional size of an object or substance. While mass and density are also related to matter, they do not encompass the entirety of what matter is.
2.
The amount of matter in an object
Correct Answer
A. Mass
Explanation
Mass is the correct answer because it refers to the amount of matter in an object. It is a measure of the total number of atoms and molecules in an object, and it remains constant regardless of the object's location or the presence of gravity. Mass is typically measured in units such as kilograms or grams.
3.
The amount of space an object takes up
Correct Answer
A. Volume
Explanation
Volume is the correct answer because it refers to the amount of space that an object occupies. It is a measure of the three-dimensional space enclosed by an object. Mass, matter, and density are not directly related to the space an object occupies. Mass refers to the amount of matter in an object, matter refers to the substance of which an object is composed, and density refers to the mass per unit volume of a substance. Therefore, volume is the most appropriate choice for describing the amount of space an object takes up.
4.
What do you use to measure mass?
Correct Answer
A. Triple Beam Balance
Explanation
A triple beam balance is used to measure mass. It consists of a beam that is supported by a fulcrum and has three sliding weights on it. The user places the object whose mass needs to be measured on one side of the balance and adjusts the weights on the other side until the beam is balanced. The sum of the weights is then used to determine the mass of the object. This makes the triple beam balance a reliable and accurate tool for measuring mass.
5.
The base unit used to measure Mass is ...
Correct Answer
A. Gram
Explanation
The base unit used to measure mass is the gram. This is a unit of measurement in the metric system that is commonly used to measure the mass of objects. It is a smaller unit than the kilogram, which is also commonly used for measuring mass. The gram is derived from the kilogram, with 1 kilogram being equal to 1000 grams.
6.
The particles found in Solids are close together.
Correct Answer
A. True
Explanation
Solids have particles that are closely packed together. This close arrangement of particles gives solids their fixed shape and volume. The particles in solids are held together by strong intermolecular forces, which prevent them from moving freely. As a result, solids are rigid and have a definite shape.
7.
The particles found in Gases are close together.
Correct Answer
A. False
Explanation
The statement is false because the particles in gases are actually far apart from each other. Gases have a high degree of freedom of movement, and the particles are not held together in a fixed arrangement like in solids or liquids. They move randomly and rapidly, filling the entire available space. This is why gases can be compressed easily and have low density compared to solids and liquids.
8.
The particles found in Liquids are closer together than those found in Gases.
Correct Answer
A. True
Explanation
In liquids, the particles are closer together compared to gases. This is because the intermolecular forces in liquids are stronger than in gases, causing the particles to be more tightly packed. In gases, the particles have more space between them and move more freely. Therefore, the statement that particles in liquids are closer together than those in gases is true.
9.
What is the smallest part of Matter (AKA "building block of Matter)?
Correct Answer
A. Atom
Explanation
An atom is the smallest part of matter and is considered the building block of matter because it is the basic unit that makes up all elements and compounds. Atoms consist of protons, neutrons, and electrons. Protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus.
10.
This is the center of every Atom.
Correct Answer
A. Nucleus
Explanation
The nucleus is the center of every atom, containing protons and neutrons. It is the densest part of the atom and carries a positive charge due to the presence of protons. Electrons, on the other hand, orbit around the nucleus in specific energy levels. Therefore, the nucleus is the correct answer as it accurately represents the central part of an atom.
11.
This is the Positive Charge Particle in an Atom.
Correct Answer
A. Proton
Explanation
A proton is a positively charged particle found in the nucleus of an atom. It has a mass of approximately 1 atomic mass unit and a charge of +1. Electrons, on the other hand, are negatively charged particles that orbit the nucleus. Neutrons are neutral particles found in the nucleus. Since the question asks for the positive charge particle, the correct answer is the proton.
12.
This is the Neutral/No-Charge Charge Particle in an Atom.
Correct Answer
A. Neutron
Explanation
Neutrons are neutral particles found in the nucleus of an atom. They have no charge, meaning they do not carry any positive or negative charge. This distinguishes them from protons, which have a positive charge, and electrons, which have a negative charge. The nucleus is the central part of an atom that contains protons and neutrons, while electrons orbit around the nucleus. Therefore, the correct answer is neutron.
13.
This is the Negative Charge Particle in an Atom.
Correct Answer
A. Electron
Explanation
The correct answer is electron. An electron is a negatively charged particle that orbits around the nucleus of an atom. It has a very small mass compared to protons and neutrons, and it carries a negative charge equal in magnitude to the positive charge of a proton. Electrons play a crucial role in determining the chemical and physical properties of atoms, as their arrangement and movement determine an atom's behavior in chemical reactions and its ability to form bonds with other atoms.
14.
Matter made of only 1 type of Atom
Correct Answer
A. Element
Explanation
An element is a type of matter that is made up of only one type of atom. This means that all the atoms in an element have the same number of protons in their nucleus. Examples of elements include hydrogen, oxygen, and carbon. Elements cannot be broken down into simpler substances by chemical means. Therefore, the given correct answer is "element".
15.
This is the organized chart of Elements.
Correct Answer
A. Periodic Table of Elements
Explanation
The correct answer is "Periodic Table of Elements" because it is the most commonly used and recognized term to refer to the organized chart of elements. The other options mentioned, such as "Periodic Chart of Elements," "Periodic Graph of Elements," and "Periodic Chapter of Elements," are not commonly used terms and may not accurately describe the organized chart of elements.
16.
Two or more atoms joined together to make a new substance ...
Correct Answer
A. Compound
Explanation
A compound is formed when two or more atoms chemically bond together to create a new substance with its own unique properties. In a compound, the atoms are held together by chemical bonds, such as covalent or ionic bonds. This distinguishes a compound from an element, which consists of only one type of atom, and a molecule, which can be a single element or a compound. Therefore, the term "compound" accurately describes the situation where two or more atoms combine to form a new substance.
17.
The smallest part of a compound ...
Correct Answer
A. Molecule
Explanation
A molecule is the smallest part of a compound that retains the chemical properties of that compound. It is made up of two or more atoms that are bonded together. Molecules can be composed of atoms of the same element or different elements. In contrast, an atom is the smallest unit of an element that retains the properties of that element. A substance refers to any matter that has a definite composition and distinct properties, which can include both elements and compounds. Therefore, out of the given options, molecule is the correct answer as it specifically refers to the smallest part of a compound.
18.
The combination of 2 or more substances ...
Correct Answer
A. Mixture
Explanation
A mixture is formed when two or more substances are combined without any chemical reaction taking place. In a mixture, the substances retain their individual properties and can be separated by physical means. This is different from a compound, which is formed when two or more elements chemically react and combine in a fixed ratio. A molecule refers to the smallest unit of a substance that retains its chemical properties, while a solution is a type of mixture where one substance is dissolved in another. Therefore, the correct answer is mixture.
19.
A mixture in which all the particles are mixed evenly ...
Correct Answer
A. Solution
Explanation
A solution is a type of mixture where all the particles are evenly mixed. In a solution, the solute (the substance being dissolved) is uniformly distributed in the solvent (the substance doing the dissolving). This results in a homogeneous mixture where the solute particles are not visible and cannot be easily separated from the solvent. Solutions can be formed with various combinations of substances, such as salt dissolved in water or sugar dissolved in coffee.
20.
To physically change the appearance of something ...
Correct Answer
A. pHysical change
Explanation
A physical change refers to a transformation in the physical properties of a substance without altering its chemical composition. In this context, physically changing the appearance of something implies that its external characteristics are being modified without any chemical reactions taking place. This could involve altering the shape, size, color, or state of matter of an object. The concept of conservation of matter, which states that matter is neither created nor destroyed in a chemical reaction, is not directly relevant to this question.
