An ideal gas expands from volume `V _(1)` to `V _(2).` This may be achieved by either of the three processes : `Delta U` be the change in internal energy of the gas, Q be the quantity of heat added to the system and W be the work done by the system on the gas. Identify which of the following statements is false for `Delta U` ?
