A) 30 K
B) 18 K
C) 50 K
D) 42 K
Correct Answer: D
Solution :
[d]\[Q={{\text{ }}_{n}}{{C}_{p}}\times 30=n\times \frac{7R}{2}\times 30\] \[\text{and }Q=n\times \frac{5R}{2}\times \Delta T\] \[\therefore n\times \frac{7R}{2}\times 30=n\times \frac{5R}{2}\times \Delta T\text{ or }\Delta T=42K.\]You need to login to perform this action.
