In moving out of a dormitory at the end of the semester

In moving out of a dormitory at the end of the semester, a student does 1.6 x 10^4 J of work. In the process, his internal energy decreases by 4.2 x 10^4 J. Determine each of the following quantities (including the algebraic sign): (a)W, (b) delta U, and (c)Q.

Solution Preview

a. This is the amount of work that the student does, W = 1.6 x 10^4 (J)

b. This is the change in internal energy (U). Because the energy is ...
