An idel gas undrgoes isothermal process ...

An idel gas undrgoes isothermal process from some initial state `i` to final state `f`. Choose the correct alternatives.

A

`dU=0`

B

`dQ=0`

C

`dQ=dU`

D

`dQ=dW`

Text Solution

Verified by Experts

The correct Answer is:
A, D
For an isothermal process change in temperature of the system `dT=0rArrT=` constant.
We know that for an ideal gas `dU` = change in internal energy `=nC_(v)" "dT=0`
[where, n is number of moles and `C_(v)` is specific heat capacity at constant volume ]
From first law of thermodynamics,
`dQ=dU+dW`
`=0+dWrArrdQ =dW `
