In the given figure an ideal gas changes its state from `A` to state `C` by two paths `ABC` and `AC`.    (i) Find the path along which work done is the least.   (ii) The internal energy of gas at `A` is `10J` and amount of heat supplied to change its state to `C` through the path `AC` is `200J`. Calculate the internal energy at `C`.   (iii) How much is the heat involved in the process `ABC` and `ADC`?
