Test Corrections: Gas Laws

Front

What are ideal gases?

Back

Ideal gases are gases that follow all assumptions of kinetic molecular theory, meaning they have no volume and do not exert intermolecular forces.

Front

What is the total pressure of a gas mixture?

Back

The total pressure of a gas mixture is the sum of the partial pressures of each gas in the mixture.

Front

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

Back

When the temperature of a gas decreases, the kinetic energy of the particles decreases, leading to a decrease in pressure.

Front

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

Back

According to Boyle's Law, if the volume of a gas decreases, the pressure increases, provided the temperature remains constant.

Front

How do you calculate the partial pressure of a gas in a mixture?

Back

The partial pressure of a gas can be calculated using the formula: P(gas) = P(total) - P(other gases).

Front

What is kinetic molecular theory?

Back

Kinetic molecular theory explains the behavior of gases, stating that gas particles are in constant motion and that their collisions with the walls of a container create pressure.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume at constant temperature (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) at constant pressure (V1/T1 = V2/T2).

Front

What is Dalton's Law of Partial Pressures?

Back

Dalton's Law states that the total pressure of a gas mixture is equal to the sum of the partial pressures of each individual gas.

Front

What is the formula for calculating total pressure in a gas mixture?

Back

Total pressure (P(total)) = P(O2) + P(N2) + P(He) + ... (sum of all partial pressures).
