Gas Laws Practice

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. (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 is held constant. (V1/T1 = V2/T2)

Front

What is the Ideal Gas Law?

Back

The Ideal Gas Law relates pressure, volume, temperature, and number of moles of a gas: PV = nRT.

Front

What is the Kinetic Molecular Theory?

Back

The Kinetic Molecular Theory explains the behavior of gases in terms of particles in motion, stating that gas particles are in constant, random motion and that they collide elastically.

Front

What is STP in gas laws?

Back

STP stands for Standard Temperature and Pressure, defined as 0°C (273.15 K) and 1 atm pressure.

Front

How do you calculate the density of a gas?

Back

Density (d) of a gas can be calculated using the formula: d = mass/volume.

Front

What is the relationship between pressure and volume in gases?

Back

Pressure and volume are inversely related; as volume increases, pressure decreases, and vice versa, assuming temperature is constant.

Front

What is the molar volume of an ideal gas at STP?

Back

The molar volume of an ideal gas at STP is approximately 22.4 L.

Front

What is the formula for calculating pressure using the Ideal Gas Law?

Back

Pressure (P) can be calculated using the formula: P = nRT/V.

Front

What does it mean for a gas to be 'ideal'?

Back

An ideal gas is a theoretical gas that perfectly follows the gas laws without deviations, meaning it has no intermolecular forces and occupies no volume.
