**1. 0.005 kg of nitrogen gas (N_2 – molecular weight 0.028 kg mol-1) are heated at**

constant volume (V = 3.5 x 10^-3 m^3) resulting in a pressure increase from an initial

value pi = 1.2 x 10^5 Pa to a final value pf = 1.8 x 10^5 Pa. Answer the following

questions:

(a).What are the initial and final temperatures of the gas?

(b). What is the change in the internal energy of the gas?

(c). What is the work done by the gas?

(d). What is the heat flow into or out of the gas during the process?

(e). What is the change in entropy of the gas?

Hi, I am having trouble getting started on the above question could somebody please help me?
