High temperature and low pressure.
High temperature because this speeds up the rate of the molecules so there is less intermolecular forces of attraction between particles.
Low pressure because the greater the distance of the particles and the less molecular forces of attraction between particles.
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.
An ideal gas conforming to the ideal gas law (PV = nRT) would behave at all conditions of temperature and pressure. However, in reality, no gas perfectly conforms to the gas laws under all conditions.
Helium is most likely to behave as an ideal gas when it is under conditions of low pressure and high temperature. Ideal gases follow the ideal gas law, which assumes the gas molecules have negligible volume and there are no intermolecular forces between them. At low pressure and high temperature, the molecules are far apart and moving quickly, closer to the assumptions of an ideal gas.
Under ideal conditions, population increases.
Helium and hydrogen show less deviation from ideal behavior because they are both light gases with weak intermolecular forces. These weak forces result in minimal interactions between gas particles, which closely resembles the assumptions of an ideal gas behavior. Additionally, the small size and simplicity of helium and hydrogen molecules make them less likely to experience significant deviations under normal 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.
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."
An ideal gas conforming to the ideal gas law (PV = nRT) would behave at all conditions of temperature and pressure. However, in reality, no gas perfectly conforms to the gas laws under all conditions.
Hydrogen is close to an ideal gas under certain conditions, particularly at low pressure and high temperature. However, deviations from ideal behavior can occur at high pressure and low temperature due to intermolecular interactions and molecular size effects.
Hydrogen gas behaves closely as an ideal gas under certain conditions, such as low pressure and high temperature. However, at very high pressures or low temperatures, hydrogen gas may deviate from ideal behavior due to intermolecular interactions.
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.
NH3, as in Ammonia, like all real gases, are not ideal. Ideal gases follow the ideal gas laws, but ammonia does not adhere to a few of them. First of all, the volume of its molecules in a container is not negliggible. Next, NH3 molecules have intermolecular hydrogen bonding, which is a strong intermolecular bond. Thus, the forces of attaction between molecules is not neglible. All real gases have a certain degree of an ideal gas, but no real gas is actually ideal, with H2 being the closest to ideal.
Helium is most likely to behave as an ideal gas when it is under conditions of low pressure and high temperature. Ideal gases follow the ideal gas law, which assumes the gas molecules have negligible volume and there are no intermolecular forces between them. At low pressure and high temperature, the molecules are far apart and moving quickly, closer to the assumptions of an ideal gas.
The gas that has properties most similar to an ideal gas among the options given is helium (He). Helium is a monatomic gas with low molecular weight and weak intermolecular forces, making it behave more closely to an ideal gas compared to the diatomic gases such as N2 and O2, or heavier gases like Xe.
Real gases behave most like ideal gases under conditions of low pressure and high temperature. At low pressures, the volume of gas molecules is significant compared to the volume of the container, and at high temperatures, intermolecular forces are minimized, allowing the gas molecules to behave more independently.
