Q137 / 160 · TS EAMCET 2023 (14 May Shift 1) · Physics

In a process, the work done by the system is equal to the decrease in its internal energy. The process that the system undergoes is

A
isothermal process
Correct answer
B
adiabatic process
C
isobaric process
D
isochoric process

Solution

According to first law of thermodynamics $d U=d Q-d W$ Since, $\mathrm{dW}=-\mathrm{dU}$ $$ \Rightarrow d Q=0 $$ Therefore, the process will be adiabatic process.

Hence, the correct answer is option: 'B'.
