Which of the following statements is NOT correct?
-
A.
The average kinetic energy of a gas is directly proportional to its temperature -
B.
At constant tempearture, the volume of a gas increases as the pressure increases -
C.
The pressure of a gas is inversely proportional to its volume -
D.
The temperature of a gas is directly proportional to its volume -
E.
The collisions of molecules with each other are elastic
Correct Answer: Option B
Explanation
Increasing the pressure confines the gas molecules to a smaller space, thereby reducing the volume. Reducing the pressure the other way round increases the volume of a gas.
