In a given process on an ideal gas, dw=0 and dq=−ve. Then for gas:
Open in App
Solution
The correct option is C the temperature will decrease
dq=dU+(−dw)
if dq=−ve, then dU=dq+dw=−ve(∵dw=0anddq=−ve)
Thus, Temprature will decrease
dq=dU+(−dw)
if dq=−ve, then dU=dq+dw=−ve(∵dw=0anddq=−ve)
Thus, Temprature will decrease
