The average degrees of freedom per molecule of a gas are 6. The gas performs 25 J of work in a process when it is expanded at constant pressure. Find the amount of heat absorbed by the gas.

Answer:

100

Solution:

$C_{p} = (\frac{f}{2} + 1) R = 4 R$ . At constant pressure $W = R Δ T$ and $Q = C_{p} Δ T$ , so $Q = 4 W = 100$ J.
