Matter And How IT Changes: Quiz!

When a liquid turns into a gas, it evaporates. This process occurs when the liquid molecules gain enough energy to overcome the attractive forces between them and escape into the surrounding environment as gas molecules. Evaporation is a phase change that typically happens at the surface of the liquid and is influenced by factors such as temperature, surface area, and the presence of air currents.

Red, hard, and round are all properties that can be associated with apples. Apples are commonly known to be red in color, especially varieties like Red Delicious or Gala. They are also known for their firm texture, making them hard to the touch. Additionally, apples are generally round in shape. Therefore, all the given properties align with the characteristics of apples.

All of the above senses can be used to determine some properties of a strawberry. Sight can help in identifying the color and overall appearance of the strawberry. Touch can provide information about the texture and firmness of the strawberry. Smell can help in detecting the fragrance and freshness of the strawberry. Therefore, all three senses - sight, touch, and smell - can be utilized to gather information about the properties of a strawberry.

The matter can be described based on its characteristics, including color, size, or shape. This means that when describing matter, you have the option to mention any or all of these features to provide a comprehensive description.

The three states of matter are solid, liquid, and gas. Solids have a fixed shape and volume, liquids have a fixed volume but can change shape, and gases have neither a fixed shape nor volume. The answer "all of the above" is correct because it includes all three states of matter mentioned in the question.

A balance is a tool used for measuring mass. It typically consists of a beam or lever that is supported at a fulcrum, with two pans or trays suspended from each end. The object whose mass is being measured is placed on one pan, while standardized weights are added to the other pan until equilibrium is achieved. The mass of the object can then be determined by the sum of the weights added. A balance is commonly used in laboratories, pharmacies, and other settings where precise measurements of mass are required.

Matter is the correct answer because it refers to the substance that all objects are made of. Matter is anything that has mass and takes up space. It includes both solid, liquid, and gas forms. Mass and volume are properties of matter, but they are not the correct answer as they do not encompass all objects.

The mass of an object is usually measured in grams. Grams is a unit of measurement in the metric system specifically used for measuring mass. It is a smaller unit compared to kilograms and is commonly used for everyday objects and substances.

Physical changes in matter involve changes in shape, color, and size. These changes do not alter the chemical composition of the substance, but only affect its physical properties. For example, melting ice to form water involves a change in shape and size, while adding food coloring to water changes its color. Therefore, all of the given options are correct as they represent different aspects of physical changes in matter.

Both a yardstick and a ruler can be used to measure length. A yardstick is a long, straight piece of wood or metal that is typically one yard (or three feet) long. It is commonly used for measuring longer lengths. On the other hand, a ruler is a shorter measuring tool, usually about 12 inches long, and is used for measuring smaller lengths. Therefore, either a yardstick or a ruler can be used to measure length.

All objects are alike in the sense that they both take up space and have weight. This means that regardless of the specific characteristics or properties of an object, all objects share the common attributes of occupying physical space and having mass.

Mass and volume are two important properties of matter that can be measured using various tools. A ruler/meter stick can be used to measure the dimensions of an object and determine its volume. A measuring cup can be used to measure the volume of liquids. A balance can be used to measure the mass of an object by comparing it to known masses. Therefore, using a ruler/meter stick, measuring cup, or balance, one can measure both mass and volume accurately.

Fur, bones, claws, and teeth are all physical components that are found in bears. These characteristics are unique to bears and help to define their physical makeup. Birds and reptiles do not possess these specific features, making bears the most appropriate answer.

Chemical changes are useful because they can be utilized to create various products such as plastics, clothing materials, and medicines. Plastics are essential in numerous industries, including packaging, construction, and electronics. Clothing materials made through chemical processes offer durability, comfort, and versatility. Medicines are developed through chemical reactions to treat illnesses and improve human health. These applications highlight the importance of chemical changes in modern society, as they contribute to advancements in technology, healthcare, and everyday products.

Matter can change from one state to another through a physical change, such as melting ice to get liquid water. Physical changes involve a change in the physical properties of a substance without altering its chemical composition. Melting is a physical change as it only involves a change in the state of water from solid to liquid, without any chemical reactions taking place. Therefore, this is the correct answer.

The correct answer is "A change in size, shape, or form." This answer is correct because physical changes refer to alterations in the physical properties of a substance without changing its chemical composition. Rusting and oxidation are examples of chemical changes, not physical changes. Burning is also a chemical change as it involves the reaction of a substance with oxygen. On the other hand, a change in size, shape, or form refers to physical changes such as melting, freezing, boiling, or dissolving, where the substance retains its chemical identity.

When a chemical change takes place, one kind of matter can change into another kind of matter. In a chemical change, the substances involved undergo a transformation at the molecular level, resulting in the formation of new substances with different properties. This can involve the breaking and forming of chemical bonds, rearrangement of atoms, or the release or absorption of energy. Examples of chemical changes include combustion, rusting, and the reaction between acids and bases. In contrast, physical changes only alter the physical properties of a substance, such as its shape, size, or state, without changing its chemical composition.

Weight is a fundamental property of matter that refers to the force exerted on an object due to gravity. It is a measure of the amount of matter in an object and is usually measured in units such as kilograms or pounds. While all matter does take up space and has volume, weight specifically refers to the force of gravity acting on an object.

Melting ice is a physical change because it involves a change in the state of matter from solid to liquid without any alteration in the chemical composition of the substance. The molecules in ice rearrange and gain enough energy to break the intermolecular forces holding them together, resulting in the formation of liquid water. No new substances are formed during this process, making it a physical change rather than a chemical change.
