Answer 2

False. All gases boil at the same temperature.

Explanation:

All pure substances that are present in a liquid and a gas state have boiling points. Some substances will decompose before they boil when the liquid is heated. So the substance has its boiling point, not its gas. If both its normal melting point and its normal boiling point are below room temperature is 20°C, the substance is a gas in normal conditions. The normal melting point of oxygen is -218°C; the normal boiling point is -189°C. Oxygen is a gas that is at room temperature.
