Problem- A) Compare a solid and a gas with respect to the arrangement of their molecules. Use this comparison to explain the effect of pressure exerted by a solid and by a gas.
B) Describe condensation (the change from gas to liquid) in terms of the kinetic molecular theory (KMT).
Please answer simply.
I am not able to get the correct answer please help me
