During low pressure, and low temperature conditions
The ideal conditions for a gas mixture containing propane to behave like an ideal gas when mixed with air are when the temperature is high, the pressure is low, and the molecules are far apart from each other. This allows the gas molecules to move freely and independently, similar to how an ideal gas behaves.
A real gas behaves most like an ideal gas at high temperatures and low pressures.
Two gases on the periodic table that behave like ideal gases are helium (He) and neon (Ne). Ideal gases follow the ideal gas law, which assumes that the gas particles are point masses and do not interact with each other. Helium and neon have low atomic masses and weak intermolecular forces, making their behavior close to ideal in most conditions.
A. Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal." 1.He(g) Of the choices listed, the helium atom is the smallest in both size and mass, and so its behavior is more "ideal."

Oxygen gas behaves least like an ideal gas at low temperatures and high pressures. At low temperatures, the gas molecules move more slowly and can interact more with each other, deviating from ideal gas behavior. At high pressures, the gas molecules are closer together and experience stronger intermolecular forces, leading to less ideal behavior.
Ideal gases are hypothetical gases that follow the gas laws perfectly under all conditions, exhibiting no intermolecular forces and occupying no volume. In contrast, non-ideal gases deviate from these behaviors due to factors such as intermolecular attractions and the volume occupied by gas molecules, especially at high pressures and low temperatures. These deviations lead to differences in properties like pressure, volume, and temperature relationships, making real gases behave differently from the ideal gas law predictions.
The molar mass of an ideal gas affects its behavior under certain conditions. Heavier gases have lower average speeds and tend to move more slowly, while lighter gases move faster. This can impact factors like pressure, volume, and temperature in a gas sample.
An ideal gas is a theoretical gas composed of a set of randomly-moving, non-interacting point particles. The ideal gas concept is useful because it obeys the ideal gas law. At normal conditions such as standard temperature and pressure, most real gases behave qualitatively like an ideal gas. Many gases such as air, nitrogen, oxygen, hydrogen, noble gases, and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances.
Almost all mixtures of gases at ordinary T and p are ideal solutions, since they behave like ideal gases. Liquid-state examples would be solutions of very closely related compounds, like ethanol and propanol, or hexane and heptane.
Under ideal conditions....forever. Corrosion is the enemy of parts like this. If you live by the Ocean, salt air will shorten the life for instance.
Real gases act least like ideal gases under conditions of high pressure and low temperature, where the gas molecules are closer together and experience intermolecular forces that are not accounted for in the ideal gas law.
