Charles' Law Practice Flashcard

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 happens to the volume of a gas when its temperature increases according to Charles' Law?

Back

The volume of the gas increases.

Front

What is the formula for Charles' Law?

Back

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

Front

In which unit must temperature be measured for gas law calculations?

Back

Temperature must be measured in Kelvin.

Front

If the temperature of a gas is doubled, what happens to its volume according to Charles' Law?

Back

The volume increases by a factor of 2.

Front

What happens to the volume of a gas when it is heated?

Back

The volume increases if the pressure remains constant.

Front

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

Back

They have a direct relationship; as one increases, the other increases.

Front

What happens to the volume of a gas when it is cooled?

Back

The volume decreases if the pressure remains constant.

Front

What is an example of Charles' Law in everyday life?

Back

Inflating a balloon on a hot day causes it to expand.

Front

What is the significance of Kelvin in gas laws?

Back

Kelvin is the absolute temperature scale used in gas law calculations.
