  • In the given an ideal gas can change its state from A to C by two paths ABC or AC . Then

    A
    If the internal energy of gas `'A'` is `10J` and the amount of heat supplied in path `AC` is `200J`, then the internal energy of gas at `'C'` is `150J`
    B
    If the internal energyof gas at `'A'` is `10J` and the amount of heat supplied in path `AC` is `200J`, then the internal energy of gas at `'C'`is `75J`
    C
    If the internal energy of gas a state `B` is `20J`. Then the amount heat supplied to the gas to go from `A` to `B` may be 5 Joule.
    D
    If the internal energy of gas at state `B` is `20J`. Then the amount of heat supplied to the gas to go from `A` and `B` must be 10 Joule
