In a closed tightly packed container, the gas is adsorbed on the surface of charcoal. If the temperature is increased, what happens to the pressure of the gas inside the container?
Increases and gradually becomes constant
Decreases and gradually becomes constant
Remains same
Increases and then decreases
On heating the closed container more gas molecules get less adsorbed and pressure increases but after a while an equilibrium is established and the pressure becomes constant.
Hence option 1 is correct.
