The Ideal Gas Law Quiz

What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K?

C. 28.2 kPa

Which proportionality applies to Avogadro's law?

D. V&N

If the pressure, volume, and the number of moles of a gas are known, which is needed to calculate the universal gas constant from the ideal gas law?

A. The temperature of the gas.

A gas has experienced a small increase in volume but has maintained the same pressure and number of moles. According to the ideal gas law, how has the temperature of the gas changed?

B. It has increased slightly.

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?

B. It stays the same.

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

C. Charles's law, Avogadro's law, and Boyle's law.

Consider the proportionality below. What does this best represent?

C. Ideal gas law.

Which law relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions?

C. Ideal gas law.

Which law relates to the ideal gas law?

C. V1/N1 = V2/N2

Avogadro's law and Charles's law describe a proportionality of the volume of a gas when the pressure is constant. Which describes the proportionality that allows these laws to be combined when describing a gas?

C. Volume is directly proportional to moles (Avogadro's law) and to temperature (Charles's law).
