Question
When an ideal diatomic gas is heated at constant pressure , the fraction of the heat energy supplied which increases the internal energy of the gas is .
Options
A.2/5
B.3/5
C.3/7
D.5/7
Solution
dQ = dW + dU
dQ = PdV + dU
dQ = nRdT + dU
dQ =
+ dU
= 
= 
dQ = PdV + dU
dQ = nRdT + dU
dQ =
+ dU = = Create a free account to view solution
