100g of N2 (M = 28 g/mol) are at an initial pressure of 1×105 Pa and an initial volume of 2×10-3 m³. The nitrogen is heated at constant volume until the pressure of the gas doubles. Answer the following 3 questions based on this scenario.
Question 16: What is the heat (in Joules) absorbed by the gas? Assume that the temperature is high enough for the vibrational states of the N2 molecules to be active.
Question 17: What is the work (in Joules) done by the gas?
Question 18: What is the change in internal energy (in Joules) of the gas?
