Question

(1) State three postulates of the kinetic energy
(2) Draw a sketch to illustrate boyle's law (3) explain what is meant by absolute zero temperature (4) equal volvolume of a gas x and oxygen are at the same pressure but temperature of 200k and 800k respectively(i) give reanson for your answer state which of the gas sample contains the greater number of molecules (ii) if the mass of one molecule of the gas x is 2•19×10^-22g determine the molar mass of x {avogadro constant =6•20×10^23}

Answer 1

Answer:

(1) 1. The molecules in a gas are small and very far apart. Most of the volume which a gas occupies is empty space.

2.Gas molecules are in constant random motion. Just as many molecules are moving in one direction as in any other.

3.Molecules can collide with each other and with the walls of the container. Collisions with the walls account for the pressure of the gas.
