Question

Oxygen gas is filled in four containers A, B, C and D having the same volume and each kept at a temperature of 30 ${}^o$C, 40 ${}^o$C, 50 ${}^o$C, 60 ${}^o$C respectively . In which one of the following containers force exerted by the gaseous particles is maximum on the walls of the container.

• A. Container A
• B. Container B
• C. Container C
• D. Container D

Answer 1

The correct option is D Container D

$\bullet$ In the gaseous state, the particles move about randomly at high speed. Due to this random movement, the particles hit on the walls of the container. This is the force exerted by gas particles on the walls of the container.
$\bullet$ At high temperature, the particles have more velocity or kinetic energy, so they hit the walls with a larger force.
Order of temperature : D>C>B>A
$\therefore$ Order of kinetic energy : D>C>B>A
​​​​​​​$\therefore$ Order of force exerted on the walls of the container : D>C>B>A
