an ideal gas operates in a carnot cycle so that it produces a net positive work of 400 joules per cycle. the maximum temperature during the cycle is 300 deg celsius and the heat lost to a low temperature bath is 600 joules per cycle.
a) what must be the temperature of the low temp bath?
b) what is the change in entropy of the gas during the isothermal expansion
Q = W = nRT ln (Vf/Vi) i don't think is use this equation as moles is not stated, volumes not given either
(entropy) deltaS = deltaQ/T
The Attempt at a Solution
i am not sure what equations to use as i think i need to consider the entire cycle not just the individual isothermic/adiabatic expansions/contractions
will the same W equation from (a) be used in part (b) because in an isothermic expansion Q = W, but again moles and volume is not given?
any help with which equation to use / approach is appreciated...
