4. A cylinder of 40 g of one of the "noble" (inert) gases is heated at constant volume.The transfer of 623.6 J of energy during the heating process results in a temperature rise of 25 K. (a) Identify the gas. (b) Determine the temperature rise that would occur if the same sample of gas were given the same amount of energy at constant pressure. Why is the temperature rise different from part (a)?
