Charles Law

Front

What does Charles's Law state?

Back

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

Front

Which two variables are related in Charles's Law?

Back

Temperature and volume.

Front

What is the formula for Charles's Law?

Back

V1/T1 = V2/T2, where V is volume and T is temperature in Kelvin.

Front

What happens to the volume of a gas if the temperature increases while pressure remains constant?

Back

The volume of the gas increases.

Front

What is the unit of temperature used in gas law equations?

Back

Kelvin (K).

Front

If the pressure of a gas is held constant, what happens to the volume when the temperature decreases?

Back

The volume decreases.

Front

What is the significance of the constant pressure in Charles's Law?

Back

Constant pressure ensures that the relationship between volume and temperature can be observed without interference from changes in pressure.

Front

How does Charles's Law apply to hot air balloons?

Back

As the air inside the balloon is heated, its volume increases, causing the balloon to rise.

Front

What is the relationship between temperature and volume in Charles's Law?

Back

They are directly proportional; as one increases, the other also increases.

Front

What must remain constant for Charles's Law to apply?

Back

Pressure must remain constant.
