What kind of gas follows all of the gas laws?

            Ideal / Perfect gas follows all of the gas laws.

Explanation:
                   Those gases which obeys Ideal gas equation are known as Ideal gases. The Ideal gas equation is a combination of all gas laws including Boyle's Law, Charle's Law and Avogadro's Law, it is mathematically expressed as

                                             P V  =  n R T

Ideal gases are termed as those gases in which the intermolecular forces are negligible, therefore, these gases doesn't interact with each other.

On the other hand, real gases can be made ideal by increasing temperature and decreasing pressure.
