Determine which of the following sets of data satisfy the first law of thermodynamics? (recall that e = total energy = u + ke + pe). a. w = 50 kj q = 170 kj deltae = 120 kj b. w = 100 btu q = -110 btu deltae = -210 btu c. w = 250 kj q = -110 kj deltae = -100 wh d. w = 44 kpa-m3 q = -84 kpa-m3 delate = 40 kn-m
