Question: Calculate E and determine whether the process is endothermic or exothermic for the following cases: (a) q = 0.763 kJ and w = -840 J

Calculate ¢E and determine whether the process is endothermic or exothermic for the following cases:
(a) q = 0.763 kJ and w = -840 J
(b) A system releases 66.1 kJ of heat to its surroundings while the surroundings do 44.0 kJ of work on the system
(c) The system absorbs 7.25 kJ of heat from the surroundings while its volume remains constant (assume that only P-V work can be done).
