We consider a thermodynamic system. If `DeltaU` represents the increase in its internal energy and W the work done by the system, which of the following statements is true?

A

`DeltaU` = dW is an isothermal process

B

`DeltaU` = -dW is an adiabatic process

C

`DeltaU` = -dW is an isothermal process

D

`DeltaU` = dW is an adiabatic process

Text Solution

Verified by Experts

The correct Answer is:
B
In an adiabatic process, dQ = 0,
`thereforedQ=dU+dW" "thereforedU=-dW`
