Which of the following statements is NOT correct?
- The average kinetic energy of a gas is directly proportional to its temperature
-
At constant temperature, the volume of a gas increases as the pressure increases
- The pressure of a gas is directly proportional to the density.
- The temperature of a gas is directly proportional to its volume
The correct answer is: B
Explanation
Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases.
Option A,C and D are correct except option B which is incorrect.
