the work and the heat per degree change of temperature for a system executing a non-flow process are given by dW/dt= 80 watt-sec/

EXPERT ANSWER dU = dQ – dW dQ = cal/C = 4.18 KJ/C ∴ dW = 80 watt -s /C = 80 J/C = 0.08 KJ/C ∴ dU/dt = 4.18 – 0.08 = 4.1 KJ/C ∴ dU = 4.1 .dT on integrating form T1 = (150 + 273) = 423 K to T2 = (250 …
