If you are given the pressure, temperature, and number of moles, what unknown variable are you able to calculate using the Ideal Gas Law?
Volume
Which of the following is NOT a point of Kinetic Molecular Theory?
I - The volume of the individual atom is negligible to the volume of the gas.
II - All collisions in a gas are inelastic.
III - Kinetic Energy is directly related to Temperature.
II - the opposite is true! In Kinetic Molecular Theory we consider all collisions to be elastic.
