Which from following statements is true about internal energy?

Options

  1. AIt increases with increase in temperature.
  2. BIt decreases with increase in temperature.
  3. CRemain constant on changing temperature.
  4. DIt is not a state function.

Correct answer

A. It increases with increase in temperature.

Step-by-step solution

The internal energy of a substance increases with increase in temperature due to increase in rotational, translational and vibrational energy of the molecule.
