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 is V1 / T1 = V2 / T2.

Front

How do you convert Celsius to Kelvin?

Back

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

Front

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

Back

The temperature in Kelvin is 393.15 K (120 + 273.15).

Front

What happens to the volume of a gas when its temperature increases at constant pressure?

Back

The volume of the gas increases.

Front

What is the new temperature of a gas if its volume changes from 400 mL to 700 mL at constant pressure?

Back

The new temperature is 414.75°C.

Front

If a gas has a volume of 3.8 L at 25°C, what will be its volume at 57°C?

Back

The volume will be 4.21 L.

Front

What is the volume of a gas at 0°C if its volume at 100°C is 1.0 L?

Back

The volume at 0°C is 0.67 L.

Front

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

Back

Volume increases as temperature increases, and vice versa, when pressure is constant.

Front

If a balloon has a volume of 0.6 L at 293 K, what will its volume be at 176°C?

Back

The volume will be 0.92 L.
