In a closed flask of one dm3,2.0g of hydrogen gas is heated from 27°C to 327°C.Which of the following is incorrect
Correct answer: D. The number of moles of the gas increases
- A. The pressure of the gas increases
- B. The kinetic energy of gas molecules increases
- C. The rate of collision increases
- D. The number of moles of the gas increases
Explanation
Increasing the temperature will increase the pressure at constant volume of gas.It will also increase kinetic energy of gases due to which number of collisions will also increase.But it has no effect on number of moles of a gas.

About Kinetic Molecular Theory
Kinetic molecular theory explains gases as rapidly moving particles separated by large distances, with negligible volume and negligible intermolecular attraction in the ideal model. It relates temperature to average kinetic energy and explains gas pressure, Boyle's and Charles's laws, diffusion, effusion and the conditions under which real gases deviate from ideal behavior.
