Nature of Matter Review

Multiple Choice

When is the Unit 1 Test?

• Never

• Matter is made up of particles, called atoms.

• These particles are in constant, random motion.

• ​The state of matter depends on the kinetic energy (temperature) of the particles.​

Kinetic Molecular Theory

​As you increase in temperature, the substance goes from a solid, to a liquid, to a gas, and then a plasma (if it is hot enough).

Multiple Choice

• Gas

Multiple Choice

If I heat a liquid and its temperature increases, what change occurs to motion of the molecules?

Multiple Choice

As matter changes state from gas to solid, the atoms have ____ kinetic energy.

• more

• less

• the same

Physical properties of matter are properties that can be measured or observed without matter changing to an entirely different substance.

​

​Physical properties

Chemical properties describe how a substance interacts with other substances to produce new substances.

Density is an important physical property of matter as it reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter has greater density.

Density

Multiple Choice

The amount of matter in a given space of volume is

• density.

• state.
