Answer: Ideal Gases
Explanation: Ideal gases are the gases which are known to obey certain kinds of gas laws and have no inter molecular forces of attraction.
Thus ideal gas equation can be written as
PV = nRT
where P = Pressure of the given gas, V = volume of the gas, n= number of moles, R = gas constant and T = temperature of the maintained gas.
On the other hand, Real gases are the one which are known to obey the ideal gas equation and its laws at high temperature and low pressure. They have sufficient amount of forces of attraction.
