A copper rod 20 cm long having a cross-sectional area of 7.0 cm2 is used to connect a boiler maintained at 100 oC to a large block of ice at 0 oC. Once a steady state is reached, what is the rate of heat flow through the rod?
A) What is the rate of change in entropy of the boiler (in W/deg)?
B) What is the rate of change in entropy of the rod (in W/deg)?
C) What is the rate of change in entropy of the ice (in W/deg)?
D) What is the rate of change in entropy of the universe due to the heat flow through the bar ?
