Question

The internal energy of an ideal gas:

• A. increases with increase in temperature
• B. decreases with increase in temperature
• C. remains unaffected with temperature
• D. can be calculated by the reaction, $E=m{c}^2$

Answer 1

The correct option is A increases with increase in temperature

The internal energy of an ideal gas increases with increase in temperature due to the increase in rotational, translational and
vibrational energy of the molecule.
