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`

Answer» Correct Answer - 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 `
