A Carnot engine has 200 g of helium as its working substance and operates between two reservoirs which are at temperatures of 500C and 30C. The initial volume of the gas is 20 litres while the volume after isothermal expansion is 60 litres.
  For one complete cycle, determine :
    A. the heat absorbed from the hot reservoir
can anyone tell me where to start with this?
imn really lost

    In a Carnot cycle, heat is absorbed from the reservoir at a constant temperature, which in this case is 500 C.

    The heat absorbed from the reservoir per cycle at 500 C is T*(change in entropy)

    Compute the change in entropy during heat absorption.

    How is the change in entory calculated?
