Which statement would be the most useful for deriving the ideal gas law?

Volume is directly proportional to the number of moles.

Volume is inversely proportional to the temperature.

Pressure is directly proportional to the volume.

Pressure is inversely proportional to the number of moles.

Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change?

It doubles.

It stays the same.

It increases greatly.

It decreases slightly.

Which laws can be combined to form the ideal gas law?

Boyle’s law and Charles’s law

Gay-Lussac’s law and Avogadro’s law

Charles’s law, Avogadro’s law, and Boyle’s law

Dalton’s law, Gay-Lussac’s law, and Avogadro’s law

Which equation agrees with the ideal gas law?
