ideal gas

Hypothetical perfect fluid

An ideal gas is a theoretical gas whose molecules occupy no volume and exert no attractive forces on each other, making its behavior perfectly predictable by simple equations.

Real gases approximate ideal behavior at low pressures and high temperatures.

The concept serves as a baseline in physics and chemistry: We'll assume an ideal gas for this calculation.
