When x kJ heat is provided to a system, work equivalent to y J is done on it. What is internal energy change during this operation?

Options

  1. A(1000 x+y) J
  2. B1000(x+y) J
  3. C(x+1000 y) J
  4. Dx+y ~ J

Correct answer

A. (1000 x+y) J

Step-by-step solution

aligned & Q =+ xkJ =1000 x J & W =+ y J aligned From I law of Thermodynamics aligned & U=Q+W & =(1000 x+y) J aligned
