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
