Question

Consider the basic postulates of kinetic molecular theory given below: The size of a gas particle is negligibly small. The average kinetic energy of a particle is proportional to its temperature in kelvins. 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

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

Step-by-step explanation:

• A particle's average kinetic energy is proportional to its kelvin temperature.

• The size of the molecule re not a factor in pressure, if it is large,e then the force will be lower, so Pressure is constant.

• The collision between particles is elastic is only temperature value-dependent.

The best answer is, The energy is proportional to temperature, so Increase in Pressure, increase in Temperature
