the intial state A has the temperature T_(A)U_(A)as the internal energy of the system . By appling the mechanical work . New state B is achieved with the temperatutre T_(B) and having the interanal energy U_(B). Given that t_(B) gt T_(A). What is the correct expression for the change in internal energy (DeltaV) ?

Answer»

`U_(B)= U_(A)`
`U_(B) -U_(A)`
`U_(A) - U_(B)`
none of these

Solution :the change in the INTERNAL ENERGY is `DeltaU=U_(B)-U_(A)`
