Question

What three assumptions about particles in a gas are made by the kinetic theory?

Answer 1

That they do not interact; collide.

That they do not lose energy.

That they are not affected by temperature ( not sure about that last one )

Answer 2

The three main assumptions, in a nutshell are:

all collisions are elastic, whether between gas molecules or gas molecules and container walls

the volume occupied by the gas molecules is small compared to the volume of the container

the average kinetic energy of the gas molecules is a function of temperature only

There are lots of other assumptions listed in the reference below that are corollaries of the above three propositions.
