    Answer:

    The increase in the internal energy of the system is 360 Joules.

    Explanation:

    Given that,

    Heat supplied to a system, Q = 292 J

    Work done on the system by its surroundings, W = 68 J

    We need to find the increase in the internal energy of the system. It can be given by first law of thermodynamics. It is given by :

    dE=dQ+dW\\\\dE=292\ J+68\ J\\\\dE=360\ J

    So, the increase in the internal energy of the system is 360 Joules. Hence, this is the required solution.
