I. First Law Problems 1. A system gains 35 J of heat, but it also does 65 J of work. Calculate AE. 2. A system evolves 50 J of heat and 75 J of work is done on the system. What is the internal energy change of the system? 3. When one mole of ice, H20(s), is converted to H2O(1) at 0C and 1 atm, 6.01 kJ of heat is absorbed by the system. The molar volume, V, for ice and water is 0.0196 L, and 0.0180 L respectively. Calculate AE and AH. [1 L'atm=101.3 J]
