A) the temperature will decrease
B) the volume will increase
C) the pressure will remain constant
D) the temperature will increase
Correct Answer: A
Solution :
[a] From the first law of thermodynamics \[dQ=dU+dW\] Here \[dW=0\] (given) \[\therefore ~dQ=dU\] Now since \[dQ<0\] (given) \[\therefore dQ\] is negative \[\Rightarrow dU=-ve\Rightarrow dU\text{ decreases}\text{.}\] \[\Rightarrow \] Temperature decreases.You need to login to perform this action.
