A) 4000 J
B) 3000 J
C) 3500 J
D) 4500 J
E) 5000J
Correct Answer: B
Solution :
Heat added to helium during expansion \[H=n{{C}_{V}}\Delta T=8\times \frac{3}{2}R\times 30\] \[\left( {{C}_{V}}for\text{ }monoatomic\text{ }gas=\frac{3}{2}R \right)\] \[=360R\] \[=360\times 8.31\text{ }J\] (R = 8.31 J/mol-K) \[\approx 3000\text{ }J\]You need to login to perform this action.
