Answer to Question #203795 in General Chemistry for lea

Question

1. What is the sign and magnitude of the heat associated with a process with 342 J of work is done and there is an increase in the internal energy of 5.43 kJ?
2. What is the sign and magnitude of the work associated with a process where the system lost 1.23 kJ of heat and the internal energy was reduced by 921 J?
3. The volume of a balloon expands by 230 mL against an atmospheric pressure of 745 mm Hg. Assuming the resistance of the latex to be negligible, how much work is associated with the process?

Answer 1

1.Magnitude of the heat(q) =+5.772KJ

2.Magnitude of the heat w=+0.309KJ

3.Work Done(W) =506.625J
