Question

As the temperature increases, average kinetic energy of molecules increases. What would be the effect of increase of temperature on pressure provided the volume is constant? 

(A) Increases 

(B) Decreases 

(C) Remains same 

(D) Becomes half

Answer 1

Correct option is: (A) Increases

Gay-Lussac's law states that at constant volume The pressure of a fixed amount of a gas is directly proportional to the temperature.

P ∝ T at constant volume.

Thus, pressure increases if the temperature is increased at a constant volume.

Answer 2

Correct option is (A) Increases
