Gas Laws Review Warmup

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. (P1V1 = P2V2)

Front

What remains constant in Boyle's Law?

Back

Temperature remains constant.

Front

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

Back

The volume increases.

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. (V1/T1 = V2/T2)

Front

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

Back

The volume increases.

Front

What is Avogadro's Law?

Back

Avogadro's Law states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules.

Front

What is the Combined Gas Law?

Back

The Combined Gas Law combines Boyle's, Charles', and Avogadro's laws and relates pressure, volume, and temperature of a gas. (P1V1/T1 = P2V2/T2)

Front

How do you convert Celsius to Kelvin?

Back

K = °C + 273

Front

What happens to the volume of a helium balloon when placed in a freezer?

Back

The balloon's volume decreases due to the decrease in temperature.

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Pressure and volume are inversely related; as one increases, the other decreases.
