Question

Quizplus · Accepted Answer

A gas is considered "ideal" if it follows the ideal gas law, which is PV=nRT. The pressure, volume, temperature, and number of moles can vary for an ideal gas, as long as they satisfy this equation. Therefore, it is not necessary for an ideal gas to exert a pressure of exactly 1 atm in a one-liter container at room temperature.
