Understanding Gas Diffusion Concepts

What is Graham's Law of Effusion?

• The rate of effusion of a gas is inversely proportional to the square root of its molar mass.

• The rate of effusion of a gas is directly proportional to its molar mass.

• The rate of effusion of a gas is inversely proportional to its volume.

• The rate of effusion of a gas is directly proportional to its temperature.

Which of the following factors does NOT affect the diffusion of gases?

• Temperature

• Pressure

• Color of the gas

• Molar mass

What is the main difference between diffusion and effusion?

• Diffusion occurs through a small hole, while effusion occurs in open space.

• Effusion occurs through a small hole, while diffusion occurs in open space.

• Diffusion involves liquid particles, while effusion involves gas particles.

• Effusion involves liquid particles, while diffusion involves gas particles.

According to Graham's Law, if Gas A has a molar mass of 4 g/mol and Gas B has a molar mass of 16 g/mol, which gas will effuse faster?

• Gas A

• Gas B

• Both gases will effuse at the same rate.

• It depends on the temperature.

Which of the following is a real-life example of gas diffusion?

• A balloon deflating over time.

• Perfume spreading in a room.

• A tire losing air through a puncture.

• A gas cylinder leaking through a valve.

What happens to the rate of diffusion if the temperature of a gas increases?

• The rate of diffusion decreases.

• The rate of diffusion remains the same.

• The rate of diffusion increases.

• The rate of diffusion becomes zero.

• Both will diffuse at the same rate.

• It depends on the pressure.

What is the formula for Graham's Law of Effusion?

Which of the following is NOT a factor affecting gas diffusion?

• Concentration gradient

• Surface area

• Volume of the container

• Type of container material

In the context of gases, what does the term "effusion" refer to?

• The mixing of gas particles in open space.

• The escape of gas particles through a tiny hole.

• The condensation of gas particles into a liquid.

• The expansion of gas particles in a closed container.
