What is the difference betweem ideal gas law and real gas law?

What is the difference between real and ideal gas?

As the particle size of an ideal gas is extremely small and the mass is almost zero and no volume Ideal gas is also considered as a point mass. ... The molecules of real gas occupy space though they are small particles and also have volume.

An ideal gas is one that follows the gas laws at all conditions of temperature and pressure. To do so, the gas would need to completely abide by the kinetic-molecular theory. A real gas is a gas that does not behave according to the assumptions of the kinetic-molecular theory.

An ideal gas is defined as a gas that obeys gas laws at all conditions of pressure and temperature while A real gas is defined as a gas that does not obey gas laws at all standard pressure and temperature conditions.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
