Gas Laws Exam 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 and the number of moles are held constant. (P1V1 = P2V2)

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 and the number of moles are held constant. (V1/T1 = V2/T2)

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.

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. (V1/n1 = V2/n2)

Front

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

Back

Pressure and volume are inversely proportional; as the volume of a gas increases, the pressure decreases, provided temperature and moles are constant.

Front

How do you calculate the number of moles of a gas using the Ideal Gas Law?

Back

To calculate moles (n), rearrange the Ideal Gas Law: n = PV/RT.

Front

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

Back

According to Charles's Law, the volume of a gas increases as the temperature increases, provided pressure is constant.

Front

What is the effect of increasing pressure on the volume of a gas?

Back

Increasing pressure on a gas decreases its volume, as described by Boyle's Law, when temperature is held constant.

Front

What is the significance of the gas constant (R) in the Ideal Gas Law?

Back

The gas constant (R) is a proportionality constant that relates the energy scale to the temperature scale in the Ideal Gas Law.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature: K = °C + 273.15.
