At a certain temperature, the degrees of freedom per molecule for gas is 8 . The gas performs 150 J of work when it expands under constant pressure. The amount of heat absorbed by the gas will be _____ J .

Correct answer

0

Step-by-step solution

For constant pressure process, Work done is given by W = n R Δ T = 150   J , here, R is gas constant. Now, for above process, f = 8 . So, specific heat at constant pressure is C P = 1 + f 2 R . Amount of heat adsorbed by the gas is Q = n C P R Δ T = f 2 + 1 n R Δ T = 8 2 + 1 150 = 750   J
