Charles laws

Front

What is Charles's Law?

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

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

Back

The volume of a gas increases when its temperature increases, provided the pressure remains constant.

Front

If the temperature of a gas is measured in Kelvin, what is the relationship between Kelvin and Celsius?

Back

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

Front

What is the formula for Charles's Law?

Back

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

Front

If the initial volume of a gas is 2.5L at 30°C, what is the final volume at 20°C?

Back

2.4L

Front

If the Kelvin temperature of a gas is doubled, how does the volume change?

Back

The volume increases by a factor of 2.

Front

What unit is used to measure temperature in Charles's Law?

Back

Kelvin (K) is used to measure temperature in Charles's Law.

Front

If the initial volume is 6.3 L at 303K, what is the final temperature if the volume is doubled?

Back

606 K

Front

What is the effect of decreasing the temperature of a gas on its volume?

Back

Decreasing the temperature of a gas will decrease its volume, assuming pressure is constant.

Front

What is the relationship between temperature and volume in gases?

Back

The relationship is direct; as temperature increases, volume increases.
