Question

In a cyclic process, a gas performs 123 J of work on its surroundings per cycle. What amount of heat, if any, transfers into or out of the gas per cycle?

123 J transfers out of the gas

123 J transfers into the gas

246 J transfers into the gas

0 J (no heat transfers)

    Answer:

    123 J transfer into the gas

    Explanation:

    Here we know that 123 J work is done by the gas on its surrounding

    So here gas is doing work against external forces

    Now for cyclic process we know that

    \Delta U = 0

    so from 1st law of thermodynamics we have

    dQ = W + \Delta U

    dQ = W

    so work done is same as the heat supplied to the system

    So correct answer is

    123 J transfer into the gas
