The given figure shown a change of state `A` to state `C` by two paths

1.	The given figure shown a change of state `A` to state `C` by two paths `ABC` and `AC` for an ideal gas. Calculate the : (a) Path along which work done is least. (b) Internal energy at `C` if the internal energy of gas at `A` is `10 J` and amount of heat supplied to change its state to `C` through the path `AC` is `200 J`. (c) Amount of heat supplied ot the gas to go from A to B, if internal energy of gas at state `B` is `10 J`.
Answer» Correct Answer - `(a) AC` is least, `(b) 170 J, (c) 10 J`
