Defintions and Basci Concepts and Laws:

1- The gas molecules are in continous random motion ( called Brownian motion) and collide with each other and with walls of the container.

2- The intermolecular spaces between gas molecules are large enough to permit gases to diffuse through each others.

3- The Brownian motion is explained by Sir William Ramzy.

4- Boyle's law :
At constant temperature, the volume of a fixed mass of a gas is inversely proportional to its pressure.

5- Charle's law :
* At constant pressure, the volume of a fixed mass of gas expand by Chapter Six : Gas Laws BR640051

of its volume at 0 ^oC for one degree raise in temperature. (voluem expansion coefficient of a gas at const. pressure / unit degree rise of temperature.

Chapter Six : Gas Laws BR-PHE12-0042

* At constant pressure, the volume of a fixed mass of gas is directly proportional to its temperature at Kelvin scale,
Chapter Six : Gas Laws BR-PHE12-0043

6- Pressure Jolly's law : * At constant volume, the pressure of a fixed mass of gas increase by Chapter Six : Gas Laws BR640051

of its pressure at O^o C for one degree raise in temperature . (The pressure expansion coefficient of a gas at const. volume / unit degree rise of temperature.
