Question

1. For the following diagrams, indicate the sign of the variable specified. surroundings system a. q is W b. w is surrounding

Answer 1

Answer #1

a) heat is transferred from system to Surroundings thus sign of q is negative.

b) work is done on the system thus w is positive.

c) delta E is towards the system thus $\Delta$ E is positive.
