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

The formula for Charles' Law is V1 / T1 = V2 / T2, where V is volume and T is temperature in Kelvin.

Front

If the temperature of a gas decreases, what happens to its volume at constant pressure?

Back

If the temperature of a gas decreases, its volume also decreases at constant pressure.

Front

What happens to the volume of a gas if its temperature is increased while keeping pressure constant?

Back

If the temperature of a gas is increased while keeping pressure constant, its volume increases.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What is the initial volume of a gas if it expands from 200 mL to 400 mL when heated from 27°C to 57°C?

Back

The initial volume of the gas is 200 mL.

Front

Calculate the new volume of a gas if its initial volume is 200 mL at 600 K and the temperature is lowered to 300 K at constant pressure.

Back

The new volume of the gas will be 100 mL.

Front

What is the volume of a gas at 25°C if it expands to 4.21 L at 57°C?

Back

The volume of the gas at 25°C is 3.8 L.

Front

If a gas has a volume of 400 mL at 120°C, what is its volume at 700 mL?

Back

The new temperature of the gas is approximately 14.75°C.

Front

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

Back

The relationship is direct; as temperature increases, volume increases, and vice versa.
