A certain mass of is taken from an initial thermodynamics state A to another state B by process I and II. In process I for the gas does 5 J of work and absorbs 4 J of heat energy. In process II, the gas absorbs 5 J of heat. The work done by the gas in process II is

When a gas is taken from one state a to another state b via one path, it absorbs 25 calories of heat while doing 70J of work. How much heat much heat has to be supplied in taking the same gas from state a to state b via another path when it performs 200J of work?

  • A perfect gas goes from state A to another state B by absorbing 8 x 10^5 J of heat and doing 6.5 x 10^5 J of external work. It is now transferred between the same two states in another process in which it absorbs 10^5 J of heat. Then in the second process,

    A
    work done on the gas is `0.5xx10^5` J
    B
    work done by gas is `0.5xx10^5` J
    C
    work done on gas is `10^5` J
    D
    work done by gas is `10^5` J

  • A perfect gas goes from state A to state B by absorbing 8 xx 10^5 joule and doing 6.5 xx 10^5 joule of external work. If it is taken from same initial state A to final state B in another process in which it absorbs 10^5 J of heat, then in the second process work done

    A
    On gas is `10^5J`
    B
    On gas is `0.5 xx 10^5J`
    C
    By gas is `10^5J`
    D
    By gas is `0.5 xx 10^5`J

  • A gas undergoes change from state A to state B. In this process, the heat absorbed and work done by the gas is 5 J and 8 J, respectively. Now gas is brought back to A by another process during which 3 J of heat is evolved. In this reverse process of B to A:

    A
    6 J of the work will be done by the gas
    B
    6 J of the work will be done by the surrounding on gas
    C
    10 J of the work will be done by the surrounding on gas
    D
    10 J of the work will be done by the gas
