An ideal gas of molecules (of mass 3.3 x 10 -27kg) is at temperature 400 K and density 0.1 kg/m3. The gas is confined within a cube of side length 2 m. What is magnitude of the average force experienced by one of the walls of this cube due to the collisions and reflections of this confined gas? ANS SHOULD BE 6.7 x10^5 N. WHAT FORMULA IS USED TO GET THIS?
