A) \[-895.8\text{ }cal\]
B) \[-1172.6\text{ }cal\]
C) \[-1381.8\text{ }cal~~~~\]
D) \[-1499.6\text{ }cal\]
Correct Answer: C
Solution :
Work done in isothermal reversible expansion of an Ideal gas \[=-2.303nRT\,\log \frac{{{P}_{1}}}{P{{ & }_{2}}}\] \[n=1,R=2,\text{ }T=273+27=300\text{ }K\] \[{{p}_{1}}=10atm,\,{{p}_{2}}=1atm\] \[W=-2.303\times 1\times 2\times 300\text{ }log\frac{10}{1}\] \[=-1381.\text{ 8c}al\] [\[\because \] log 10=1]You need to login to perform this action.
