5. A sample of N2 gas at 298 K and 1 atm. The diameter of N2 molecule is d = 3.6 × 10-10 m. (1) Calculate the collisions per second that one molecule of N2 make. (II) Calculate the mean free path 2 in meter. 6. An ideal gas has absorbed 900 J as a heat energy and the volume of the gas was decreased from 20 L to 10 L at constant external pressure of 5 atm. (1) The work done on the system (in J) in this process is: (II) The internal energy change (AU) of the system (in J) in this process is: 7. A cylinder with a piston contained 5 mole of helium (He). The system allowed to expand at constant pressure after adsorbing 25 kJ energy as a heat. (Knowing that Cy =12.47 J/mol.K) (1) Calculate AH (in J) for the process? (II) Calculate AU (in kJ) for the process?
