Define what is the internal energy of gas x

Reference no: EM13263014

A box of volume 20.0 L contains 1.50 moles of an ideal gas. This gas initially consists of a single molecular species, X (molar mass of 42.0 g/mol), at a temperature of 25.0 °C.

1. (a) What is the root mean square speed in 3-dimensions of the molecules of gas X?

1. (b) What is the internal energy of gas X?

1. (c) Suppose that you raise the temperature, T, of gas X by adding 1.00 kJ of heat total to the box and its contents at constant volume. If the heat capacity of the box is CV = 15.0 J/K, what would you expect the pressure of the gas to be after adding this heat? You may assume that no heat leaks out of the box or gas into the surroundings after the heat has been added.
