Question

The first law of thermodynamics in isothermal process is

Answer 1

Answer:

basic equation for thermodynamics is du =dq+ dw but for isothermal process as temperature constant then du =-dw

Answer 2

Answer:

Here is your answer mate.

Since it is an ISOTHERMAL PROCESS temperature remains constant. So dT=0

We know that dU = nCvdT

This implies that dU is 0.

Thus, The first law of thermodynamics can be stated as

dQ =dU+dW

dQ=dW
