A cup of coffee (12oz) 0.0125 ft^3 that is at 140 degrees F sits on a desk. After some negligable time the final temperature is 80 degrees F, and the outer surface of the cup has an average temperature of 95 degrees F during the cooling process.

Calculate:

A The amount of heat transfer from the coffee, in Btu.

B The entropy produced during the process, But/degrees R.
