Question

please include detailed explanation and solution, I am stuck. thank you!!

12/10/2019 Assignment Set Tool Suppose that we use a heater to boil liquid nitrogen (N2 molecules). 4480 J of heat turns 20 g of liquid nitrogen into gas. Note that the latent heat is equal to the change in enthalpy, and that liquid nitrogen boils at 77 K. The system is kept at a constant pressure of 1 atm. 20) Assuming that you can treat the gas as ideal gas and that the volume of the liquid compute the binding energy of a nitrogen molecule in the liquid. (the binding energy is the difference in internal energy per molecule between the liquid and gas) approximately zero, a. 9.4 x 10-21 J b. 3.8 х 1027 J c. 4.2 x 10-18 J d. 10-20 J e. 2.1 x 10-19 J 385 e.Ko
