SUMMARY
The discussion focuses on calculating the force exerted by a small sample of gas contained in a cube measuring 10.0 cm on each edge, filled with air at atmospheric pressure (1 atm) and a temperature of 300K. Using the Ideal Gas Law (PV=nRT) and the conversion of pressure from atmospheres to Pascals (1 atm = 1.013 x 10^5 N/m²), participants confirmed that the force exerted on each face of the cube is 1013 Newtons. The underlying physical reason for this significant force from a small gas sample is attributed to the high number of gas molecules colliding with the cube's walls at high velocities, resulting in substantial pressure.
