Calculate ΔE, and determine whether the process is endothermic or exothermic for the following cases.
a. Calculate ΔE for a system that absorbs 661.0 kJ of heat from its surroundings and does 277.0 kJ of work on its surroundings.
b. Calculate ΔE, if q= 1.60 kJ and w= -657 J . Express your answer using two significant figures.
c. Calculate ΔE, if the system releases 56.5 kJ of heat while doing 13.0 kJ of work on the surroundings. Express your answer using three significant figures.
