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. Decrease
• C. Remains same
• D. Becomes half

Answer 1

Answer: (A)

Increases

Answer 2

: Gay lussac’s law states that at constant volume, pressure of a fixed amount of a gas varies directly with the temperature.

$\therefore \mathrm { P } \propto \mathrm { T }$ (at constant volume)

Thus, if temperature is increase at constant volume pressure increases.
