II. Answer the following problems. Show your solution. 1. A gas in a closed container is heated with 10J of energy causing the lid of the container to rise 2m with 3N of force. What is the total change in energy of the system? 2. A gas in a system has constant pressure. The surroundings around the system lose 62J of heat and do 474J of work onto the system. What is the internal energy of the system?

1. A gas in a closed container is heated with 10J of energy causing the lid of the container to rise 2m with 3N of force. What is the total change in energy of the system?
2. A gas in a system has constant pressure. The surroundings around the system lose 62J of heat and do 474J of work onto the system. What is the internal energy of the system?
3. What is the change in the internal energy of the system if 2000 J of heat leaves the system and 2500 J of work is done on the system?
4. 3000J of heat is added to a system and 2500J of work is done by the system. What is the change in energy of the system?
5. 60J of work is done on the gas, and the gas loses 150J of heat to its surrounding. What is the change in internal energy?
