Answer to Question #158085 in Organic Chemistry for Priya

Question

192j of heat was supplied to a thermodynamic system and it's internal energy was found to decrease by 22J . calculate the amount of associated work and state whether the work was done by the system or done on the system.

Answer 1

dU = dQ + dW

-22 = 192 + dW

dW = -214J

dW < 0 so work is done by the system
