Particle Motion/ Thermal Energy

Front

What is a solid?

Back

A state of matter with a fixed shape and a fixed volume.

Front

What happens when a gas loses energy?

Back

It can condense into a liquid.

Front

What is thermal energy transfer?

Back

The movement of energy from one object to another due to a temperature difference.

Front

What occurs during condensation?

Back

Gas loses energy and changes into a liquid.

Front

What is the relationship between temperature and particle energy?

Back

At higher temperatures, particles in an object have more energy.

Front

How does particle motion differ in solids, liquids, and gases?

Back

Solids have tightly packed particles that vibrate in place, liquids have particles that are close but can move past each other, and gases have particles that are far apart and move freely.

Front

What is the average particle motion in water at the same temperature?

Back

Particles in both samples have the same average speed and spacing regardless of the volume.

Front

What is the effect of temperature on gas volume?

Back

As temperature increases, the volume of a gas typically increases (Charles's Law).

Front

What is freezing?

Back

The process where a liquid loses energy and becomes a solid.

Front

What is melting?

Back

The process where a solid gains energy and becomes a liquid.
