1.  Suppose your work is done to compress a gas is 50 J. If 100 J of heat is lost in the process, what is the change in the internal energy of the gas?
Your response must be at least 75 words in length and should include any equations that are needed to answer the problem.

2.  A system does 100 J of work to its surroundings and gains 50 J of heat in the process. Calculate the change in the internal energy of the system. Determine if the internal energy is increased or decreased during the process.
Your response must be at least 75 words in length and should include any equations that are needed to answer the problem.
