Krypton is contained in a closed cylinder fitted with a weightless piston at 63 K and 1 bar. Heat is added under constant pressure until the volume has doubled in size. What is the change in the molar internal energy (Δ�)? Assume krypton is an ideal gas. From Appendix B in the text, we can assume the heat capacity of krypton is independent of temperature and ��=2.5� , where R is the molar gas constant �=8.314 J/(mol K). For an ideal gas, recall ��=��−�=1.5�. Report your answer in units of kJ/mol using three decimal places.
