Gas Laws and Molecular Behavior

Front

What happens to gas pressure when the gas is heated?

Back

The pressure increases because the gas molecules collide more often with the container.

Front

Which state of matter has the most molecular motion?

Back

Plasma has the most molecular motion.

Front

What is a characteristic property of liquids regarding their shape and volume?

Back

Liquids take the shape of their container but have a constant volume.

Front

Why does temperature not increase during a phase change?

Back

The energy that causes the temperature to increase is absorbed by the molecules during a phase change.

Front

How do gas particles move?

Back

Gas particles move freely and randomly in all directions.

Front

What is the relationship between temperature and molecular motion in gases?

Back

As temperature increases, molecular motion in gases increases.

Front

What is the definition of a gas?

Back

A state of matter that has no definite shape or volume and expands to fill its container.

Front

What is the effect of pressure on gas volume?

Back

According to Boyle's Law, as pressure increases, the volume of a gas decreases if the temperature is constant.

Front

What is Charles's Law?

Back

Charles's Law states that the volume of a gas is directly proportional to its temperature when pressure is held constant.

Front

What is the definition of a phase change?

Back

A phase change is the transition of a substance from one state of matter to another, such as solid to liquid.
