What happens to the rate of diffusion of different gases in a rigid vessel at room temperature?

Back

The rate of diffusion differs for each gas, but the overall kinetic energy of the system remains constant.

In the Maxwell–Boltzmann distribution, which letter represents the mean energy of the molecules at a higher temperature?

Back

S

What is a hypothetical gas that perfectly fits all the assumptions of the kinetic molecular theory called?

Back

Ideal gas

Front

What are the rates of effusion of different gases proportional to?

Back

Particle velocities.

Front

If you have 1 mole of helium and 1 mole of oxygen at STP, what can be said about the volumes of the balloons containing these gases?

Back

The balloons will have the same volume.

Front

What is the definition of an ideal gas?

Back

An ideal gas is a hypothetical gas that perfectly follows the gas laws and the kinetic molecular theory.

Front

What is the relationship between temperature and the kinetic energy of gas molecules?

Back

As temperature increases, the average kinetic energy of gas molecules also increases.

Front

What does the kinetic molecular theory state about gas particles?

Back

Gas particles are in constant random motion and collide elastically with each other and the walls of their container.

Front

How does the volume of a gas change with temperature at constant pressure?

Back

According to Charles's Law, the volume of a gas increases with an increase in temperature at constant pressure.

Front

What is Graham's Law of Effusion?

Back

Graham's Law states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
