Properties of Matter Quizs

Sign not necessarily indicating a chemical change

• Change in state

• Formation of a precipitate

• Color change

• Temperature change

Difference between physical and chemical change

• New properties of the matter are observed in a chemical change

• Physical changes do not alter the chemical composition of a substance

• Chemical changes are always reversible

• Physical changes result in the formation of new substances

What has mass and takes up space

• Energy

• Matter

• Light

• Sound

What happens to the molecules during a physical change?

• The molecules change into different substances.

• The arrangement of molecules changes, but the molecules themselves do not change.

• The molecules are destroyed and cannot be recovered.

• The molecules gain or lose mass during the change.

What is a chemical property?

• A characteristic that can only be observed during a chemical change, such as flammability.

• A property that can be observed without changing the substance, like color.

• A measurement of how much matter is in an object, known as mass.

• A characteristic that describes how a substance interacts with other substances, like boiling point.

During a physical change, the identity of matter

• Changes completely

• Does not change

• Partially changes

• Becomes a different substance

Indicator of a chemical change

• A new substance has been formed

• The temperature remains constant

• The color of the substance stays the same

• The mass of the substance increases

A melting ice cube is an example of a physical change because

• The form, not the identity, of the substance changes

• The chemical composition of the substance changes

• The temperature of the substance increases

• The substance becomes a gas

An example of a physical change is

• Melting ice

• Burning wood

• Rusting iron

• Cooking an egg

Malleability is an example of

• A physical property

• A chemical property

• A biological property

• A mechanical property
