A 10.0 L cylinder with a movable piston exerts 3.00 atm of pressure. What will happen to the pressure if the volume of the container increases to 20.0 L?

A sealed container with a movable piston contains a gas with a pressure of 1380 torr, a volume of 820 mL and a temperature of 31°C. What would the volume be if the new pressure is now 2.83 atm, while the temperature decreased to 25°C?

Which assumptions of the kinetic–molecular theory explain the behavior of gases described by Charles's law? Explain your answer.

Which assumptions of the kinetic–molecular theory explain the behavior of gases described by Gay-Lussac's law? Explain your answer.

A balloon is filled with helium gas with a partial pressure of 1.00 atm and neon gas with a partial pressure of 0.50 atm. For each of the following changes (a to e) of the initial balloon, select the diagram (A, B, or C) that shows the final volume of the balloon:

c. All of the neon gas is removed (T and P do not change).

Indicate if pressure increases, decreases, or stays the same in each of the following:

a.

Explain Avogadro's law using the kinetic–molecular theory of gases.
