Gas Laws Review

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant. If pressure increases, volume decreases, and vice versa.

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. If volume increases, temperature increases.

Front

What is the Ideal Gas Law?

Back

The Ideal Gas Law is a fundamental equation that relates pressure (P), volume (V), temperature (T), and the number of moles (n) of a gas: PV = nRT, where R is the ideal gas constant.

How do you convert Celsius to Kelvin?

Back

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

Front

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

Back

According to Charles' Law, the volume of a gas increases when its temperature increases at constant pressure.

Front

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

Back

According to Boyle's Law, the pressure of a gas increases when its volume decreases at constant temperature.

Front

What is the relationship between pressure and temperature in a gas?

Back

According to Gay-Lussac's Law, the pressure of a gas is directly proportional to its temperature (in Kelvin) when volume is held constant.

Front

If a gas occupies 4L at 300 kPa, what will its volume be at 140 kPa and 100K?

Back

The volume will be 4.3L.

Front

If the pressure of a gas increases from 200 kPa to 600 kPa, what is the initial temperature if the final temperature is 300 K?

Back

The initial temperature is 100 K.

Front

What is the formula for calculating the new volume of a gas when pressure changes?

Back

The formula is P1V1 = P2V2, where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.
