A. The size of a gas particle is negligibly small.
B. The average kinetic energy of a particle is proportional to its temperature in kelvins.
C. The collision of one particle with another (or with the walls of its container) is completely elastic.

Which postulate(s) are needed to explain the increase in pressure of a gas with temperature?

Answer 1

Which postulate(s) are needed to explain the increase in pressure of a gas with temperature?

increase in pressure will requires -->

B. The average kinetic energy of a particle is proportional to its temperature in kelvins.

the size of molecule re not a factor in pressure, if it is larg,e then force will be lower, so P is constatn

the collision between particle is ellastic is only temperature value dependent.

Best answer is therefore B, the energy is proportional to temperature, so Increase in P, incresa in T
