Earth Science Kinetic Molecular Theory

Front

What happens to particles when thermal energy is added?

Back

The particles move faster and the temperature rises.

Front

Which state of matter generally has the least amount of energy?

Back

Solids.

Front

What properties describe a solid?

Back

Solids have a definite shape and volume.

Front

What happens to pressure when volume decreases at a constant temperature?

Back

The pressure increases.

Front

What are the three factors that can increase the pressure of a gas?

Back

Increase the temperature, decrease the volume, or pump in more gas.

Front

Define Kinetic Molecular Theory.

Back

Kinetic Molecular Theory explains that matter is made up of particles that are in constant motion.

Front

How do gas particles behave compared to solid and liquid particles?

Back

Gas particles move freely and are far apart, while solid particles are closely packed and vibrate in place.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of particles also increases.

Front

What happens to the motion of particles in a solid when heat is applied?

Back

The particles vibrate faster.

Front

What is the effect of decreasing the volume of a gas on its pressure?

Back

Decreasing the volume increases the pressure.
