Acertain amount of water of heat capacity c is at a temperature of 0°c. it is placed in contact with a heat bath at 100° c and two come into thermal equilibrium 1. what is the entropy change of the universe? 2. the process is now divided into two stages: first the water is placed in contact with a heat bath at 50° c and comes into thermal equilibrium; then it is placed in contact with the heat bath at 100 c. what is the entropy change of the universe? 3. the process is divided into four stages with heat baths at 25, 50, 75, m and 100°c. what is the entropy change of the universe in this case? 4. if we were to continue this subdivision into an infinite number of heat baths what would be the entropy change of the universe?
