Question

what is ideal gas

Answer 1

An ideal gas is a theoretical gas composed of a collection of randomly-moving particles that do not interact with each other except during elastic collisions. In an ideal gas, the particles have negligible volume and do not exert any forces on each other. The behavior of an ideal gas is described by the ideal gas law, which relates the pressure, volume, temperature, and amount of gas in a system. While real gases do not behave exactly like ideal gases, the concept of an ideal gas is useful for simplifying calculations and understanding the behavior of gases in various conditions.
