Table salt is an example of a ____________________.
- A.
Heterogeneous mixture
- B.
Solution
- C.
Compound
- D.
Element
Correct Answer
C. CompoundExplanation
Table salt, or sodium chloride (NaCl), is an example of a compound. A compound is a substance made up of two or more different elements chemically bonded together. In the case of table salt, sodium and chlorine atoms combine to form a stable compound with distinct properties and a fixed ratio of elements. It is not a heterogeneous mixture, which consists of visibly different substances, nor is it an element, which cannot be broken down into simpler substances. A solution, on the other hand, is a homogeneous mixture of two or more substances, and table salt does not fit this description either.Rate this question:

New substances are always formed when matter undergoes a ____________________.
- A.
Change in shape
- B.
Physical change
- C.
Change in temperature
- D.
Chemical change
Correct Answer
D. Chemical changeExplanation
When matter undergoes a chemical change, new substances are always formed. This is because a chemical change involves a rearrangement of atoms and the breaking and forming of chemical bonds. This results in the creation of new substances with different chemical properties than the original matter. In contrast, a physical change only affects the physical properties of matter, such as its shape or state, without creating new substances. Therefore, the correct answer is chemical change.Rate this question:

Atoms that combine to form larger particles are called ____________________.
- A.
Elements
- B.
Substances
- C.
Molecules
- D.
Chemical bonds
Correct Answer
C. MoleculesExplanation
Molecules are formed when atoms combine together. Molecules are the smallest units of a substance that retain the chemical properties of that substance. Therefore, molecules are the correct answer as they refer to the atoms that combine to form larger particles. Elements are pure substances made up of only one type of atom. Substances is a general term that can refer to any form of matter. Chemical bonds are the forces that hold atoms together in a molecule, but they are not the actual particles formed.Rate this question:

Density
Correct Answer
C. WeightExplanation
Weight is the correct answer because it refers to the force of gravity acting on an object. Weight is dependent on the mass of the object and the acceleration due to gravity. It is a measure of the gravitational force pulling the object towards the center of the Earth. The weight of an object can change depending on the location, as the acceleration due to gravity varies.Rate this question:

Correct Answer
C. MassExplanation
Mass is the correct answer because it is a measure of the amount of matter an object contains. It is different from weight, which is the force exerted on an object due to gravity, and volume, which is the amount of space occupied by an object. The melting point is a characteristic property of a substance, not a measure of the amount of matter in an object.Rate this question:

- A.
Mass
- B.
Volume
- C.
Weight
- D.
Density
Correct Answer
D. DensityExplanation
Density is the measurement of how much mass is contained in a given volume. It is a property of matter that describes how closely packed the particles are in a substance. The formula for density is mass divided by volume. By calculating density, we can determine if a substance will sink or float in another substance, as objects with higher density than the surrounding fluid will sink, while objects with lower density will float.Rate this question:

The volume of an irregular object can be measured by
- A.
Multiplying the object’s length, width, and height.
- B.
Dividing the object’s density by its mass.
- C.
Submerging the object in water in a graduated cylinder.
- D.
Placing the object on a triple-beam balance.
Correct Answer
C. Submerging the object in water in a graduated cylinder.Explanation
Submerging the object in water in a graduated cylinder is the correct answer because it follows Archimedes' principle. When an object is submerged in a fluid, it displaces an amount of fluid equal to its own volume. By measuring the volume of water displaced by the object in the graduated cylinder, we can determine the volume of the object. This method is particularly useful for irregularly shaped objects that cannot be easily measured using traditional length, width, and height measurements.Rate this question:

Anything that has mass and takes up space is called
- A.
Matter
- B.
Density
- C.
Heterogeneous.
- D.
Homogeneous.
Correct Answer
A. MatterExplanation
Matter refers to anything that has mass and occupies space. It includes both tangible objects and intangible substances like gases and liquids. The other options, density, heterogeneous, and homogeneous, do not encompass the broad definition of matter. Density is a measure of how much mass is contained in a given volume, while heterogeneous and homogeneous refer to the uniformity or lack thereof in the composition of a substance or mixture. Therefore, matter is the correct answer as it encompasses all objects and substances that possess mass and occupy space.Rate this question:

How would you calculate the density of an object?
- A.
Divide its weight by its volume.
- B.
Divide its mass by its volume.
- C.
Multiply its volume times its mass.
- D.
Multiply its weight times its mass.
Correct Answer
B. Divide its mass by its volume.Explanation
To calculate the density of an object, you need to divide its mass by its volume. Density is defined as the mass of an object per unit volume. By dividing the mass by the volume, you can determine how much mass is packed into a given amount of space. This calculation allows you to compare the compactness or heaviness of different objects, regardless of their size.Rate this question:
