A system takes in 200 J of heat while undergoing an isothermal change of state at 500 K. What is ΔU, ΔS, W, and Q for this change of state?

A. ΔU = 0, ΔS = 1/2 J/K, W = 200 J, Q = 200 J

B. ΔU = 0, ΔS = 2/5 J/K, W = -200 J, Q = -200 J

C. ΔU = 200 J, ΔS = 1/2 J/K, W = -0, Q = 200 J

D. ΔU = 0, ΔS = 2/5 J/K, W = -200 J, Q = 200 J
