An ideal gas undergoes isothermal process from some initial state `i` to final state `f`. Choose the correct alternatives.A. dU=0B. dQ=0C. dQ=dUD. dQ=dW |
Answer» Correct Answer - A::D For an isotehrmal 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=dQ` |
