The internal energy of an ideal gas is U1 = 290J. Determine the internal energy of the gas after imparting to it the amount of heat Q = 310J and making the force of its pressure work A = 400J.
Given: U1 = 290J Q2 = 310 J A2 = 400J
Find: ∆U-?
Decision:
∆U = U2-U1; U2 = A2-Q2; => ∆U = (A2 + Q3) -U1 = (400 + 310) -290 = 420 (J)
Answer: 420 J
