The concept of an ideal gas is used to explain(1) the mass of a gas sample(2) the behavior of a gas sample(3) why some gases are monatomic(4) why some gases are diatomic

Ideal gas is used to explain the behavior of a gas sample. In ideal gas law, the equation is PV=nRT where R has a constant of 0.0821L.atm/mol.K. It can explain the behaviior of a gas in three types: mole, mass and density. The ideal gas often observed in a high temperature with low pressure as to potential energy becomes less significant compared to the kinetic energy.

The answer for this question is d. none of these

Ibelieve it's celsius. hope this .
