Question
Hey how would I solve this? In moving out of a dormitory at the end of the semester, astudent does 2.78 x 104 J of work. In the process, hisinternal energy decreases by 5.06 x 104 J. Determineeach of the following quantities (including the algebraic sign):(a)W,(b)U, and(c)Q. Thank you! Hey how would I solve this?

Work dine by the student W = 2.78*104 J internal energy U = 5.06*104 J According to first law ofthermodynamics Q = W + U =(5.06+2.78 ) 104 J = 7.84*104 J
