Which of the following equations does not correctly represent the first law of thermodynamcis?

A

Isothermal process : q=-w

B

Cyclic process : q=-w

C

Isochoric process : `DeltaU=q`

D

Adiabatic process : `DeltaU=-w`

Text Solution

Verified by Experts

The correct Answer is:
D
In adiabatic process ltBrgt `therefore` from `DeltaU=q-w`
Work is done by the system,
`DeltaU=-w` for adiabatic process.
