ICP Chapter 3 Test

Front

What does temperature describe in terms of particles?

Back

Temperature describes the motion of particles.

Front

What process causes a material to change state from a solid to a liquid?

Back

Adding heat.

Front

What happens to particles when the temperature of matter decreases?

Back

The particles slow down and move closer together.

Front

What does Charles' Law state?

Back

As volume goes up, temperature goes up.

Front

Do all phase changes require energy to be absorbed or removed?

Back

True.

Front

Define temperature in the context of particle motion.

Back

Temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is the effect of adding heat to a solid?

Back

It can cause the solid to melt into a liquid.

Front

Explain the relationship between pressure and volume according to Boyle's Law.

Back

As pressure goes up, volume goes down, provided the temperature remains constant.

Front

What is the significance of energy in phase changes?

Back

Energy must be absorbed or released for a substance to change from one state to another.

Front

Describe what happens to gas particles when they are cooled.

Back

Gas particles slow down and come closer together, potentially condensing into a liquid.
