Which of the following statements is NOT correct?
The average kinetic energy of a gas is directly proportional to its temperature
At constant tempearture, the volume of a gas increases as the pressure increases
The pressure of a gas is inversely proportional to the density
The temperature of a gas is directly proportional to its volume
Correct answer is B
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.
