If 150 ~J of heat is added to a system and the work done by the system is 110 ~J , then change in internal energy will be

Options

  1. A150 J
  2. B110 J
  3. C260 J
  4. D40 J

Correct answer

D. 40 J

Step-by-step solution

According to the first law of thermodynamics, the change in internal energy U is given by the equation: U = Q - W where Q is the heat added to the system and W is the work done by the system. Given values are Q = 150 J and W = 110 J . Substituting these values into the equation: U = 150 J - 110 J = 40 J Answer: 40 J
