Entropy Question

Question

Suppose a heat source generates heat at a rate of 79.0 W (1 W = 1 J/s). How much entropy does this produce per hour in the surroundings at 29.5 °C? Assume the heat transfer is reversible.

Change in S = ________ J/K*hour

Answer 1

79.0 W x 1 Js-/W x 60 s/min x 60 min/hr x 1/302K = 942 J/K-hour
