Write a computer program to solve Problem 6.63 using constant specific heat for both the sand and the liquid water. Let the amount and the initial temperatures be input variables.
Problem 6.63
A foundry form box with 25 kg of 200?C hot sand is dumped into a bucket with 50 L water at 15?C. Assuming no heat transfer with the surroundings and no boiling away of liquid water, calculate the net entropy change for the mass.
