a. A cylinder contains 1.0 mol of an ideal gas. The gas is heated while the volume of the cylinder remains constant. Calculate the energy required to raise the temperature of the gas by 1.0 °C.

b. Calculate the root-mean-square speed of a molecule of hydrogen-1 at a temperature of 100 °C.

(Mass of a hydrogen molecule = 3.34 × 10⁻²⁷ kg.)

c. Calculate, for oxygen and hydrogen at the same temperature, the ratio.

Root mean square speed of a hydrogen molecule / Root mean square speed of an oxygen molecule (Mass of an oxygen molecule = 5.31 × 10⁻²⁶ kg.)
