A Carnot engine has 200 g of helium as its working substance and operates between two reservoirs which are at temperatures of 500C and 30C. 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?
