Unit 1: Density, KMT, Gas Laws, and Weather

Front

What is the phase change of a solid to a liquid?

Back

melting

Front

If the absolute (Kelvin) temperature of a gas is tripled, what happens to its volume?

Back

The volume will be 3 times what it was originally.

Front

What causes gas pressure?

Back

Gas pressure is caused by gas molecules colliding with surfaces.

Front

Which of the following is true about the behavior of gases?

Back

All of the above.

Front

What is not true about the volume of a gas compared to liquids and solids?

Back

The volume is about 10 times greater than that occupied by an equal number of particles in the liquid or solid state.

Front

What is the definition of density?

Back

Density is the mass of an object divided by its volume.

Front

How does temperature affect the volume of a gas according to Charles's Law?

Back

As temperature increases, the volume of a gas increases, provided pressure is constant.

Front

What is the Kinetic Molecular Theory (KMT)?

Back

KMT is a theory that explains the behavior of gases in terms of particles in constant motion.

Front

What happens to gas molecules when temperature increases?

Back

Gas molecules move faster and collide more frequently.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature.
