A 85 cubic meter tank of nitrogen is at 60C(Celsius) and 500kPa pressure. (1) calculate the rms velocity for the nitrogen molecules (2) calculate the average translational and rotational kinetic energy of the molecules. (3) calculate the total translational and total rotational kinetic energy of the entire sample. (4) If the volume remains constant and the temperature increases to 80C, what will be the pressure?
