Flashcard on Charles' Law

Front

What is Charles' Law?

Back

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

Front

What is the formula for Charles' 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 when the temperature increases?

Back

The volume of the gas increases if the pressure remains constant.

Front

What temperature scale must be used when applying Charles' Law?

Back

Kelvin (K) must be used.

Front

Who proposed Charles' Law?

Back

Jacques Charles, a French physicist, proposed Charles' Law in 1787.

Front

What is the relationship between volume and temperature in gases at constant pressure?

Back

As temperature increases, volume also increases.

Front

What happens to the volume of a gas when the temperature decreases?

Back

The volume of the gas decreases if the pressure remains constant.

Front

Why is it important to use Kelvin in gas law calculations?

Back

Kelvin is important because it is an absolute temperature scale, ensuring that temperature values are always positive.

Front

What is the significance of the direct proportionality in Charles' Law?

Back

It means that if one variable increases, the other variable also increases at a constant rate.

Front

Can Charles' Law be applied to liquids?

Back

No, Charles' Law applies only to gases.
