W = nR Δ T =150 J Q =(( f /2)+1) nR Δ T =((8/2)+1) 150=750 J

Q. 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 ...... $J$ .

$W = n R Δ T = 150 J$
$Q = (\frac{f}{2} + 1) n R Δ T = (\frac{8}{2} + 1) 150 = 750 J$

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

W=nRΔT=150J Q=(2f​+1)nRΔT=(28​+1)150=750J
