A) 100 R
B) 150 R
C) 300 R
D) 500 R
Correct Answer: C
Solution :
[c] If a gas is heated at constant volume then no work is done. The heat supplied is given by \[dQ=n{{C}_{v}}dT\] But \[{{C}_{v}}=\frac{f}{2}R\] where \[f\] is the degree of freedom of the gas \[\therefore \] \[dQ=\frac{nfRdT}{2}\] \[=\frac{2\times 3\times R\times (373-273)}{2}=300\,R\]You need to login to perform this action.
