1. The problem statement, all variables and given/known data In an ideal gas at temperature T, the average force that a molecule applies on the walls of a closed container depends on T as Tq. A good estimate for q is: A. 2 B. 1 C. 1/2 D. 1/4 2. Relevant equations PV= nRT I think, Volume of container and moles are constant. So P ∝ T 3. The attempt at a solution Answer should be B. 1, as force = pressure* area. Here all would be ideal case. But it is C. 1/2. Why?
