    Answer:

    W provides energy output, while Q provides energy input and They are equal in magnitude

    Explanation:

    ISOTHERMAL EXPANSION is thermodynamic process, where there is no change in the temperature the system.

    “Q” means heat while “W” means work.

    From the first law of thermodynamics,

    dU = dQ – dW

    Where

    dW = pdV

    FOR ISOTHERMAL process

    dU = 0 ( there is no change internal energy and the system is loosing the internal energy due to work “W”)

    dQ – dW=0

    dQ=dW

    W=Q (for an ideal gas)

    *Therefore both Q and W are equal in magnitude because the system needs more internal energy due to loss of energy during Work.

    In conclusion “W” provides energy output, while Q provides energy input.
