Directions: Calculate the change in energy for the following processes. Determine if the process is endothermic or exothermic..
1. Calculate the change in the internal energy of a system it 5000 of heat is absorbed by the system and if 700J of work is done on the system,
2. The system releases 600J of heat energy and 200 of work is done by the system. Calculate the change in the internal energy of the system
3. What is the change in the internal energy of the system if the surroundings gain 450J of heat energy and if 670J of work is performed by the surroundings?
4. What is the change in the internal energy of the system if the surroundings absorbed 600J of heat energy and if the system does 550J of work on the surroundings?
