What is defined as the temperature at which a liquid converts to gas at vapor pressure equal to atmospheric pressure?

• A. Flash point
• B. Boiling point
• C. Fire point
• D. Freezing point

Answer: (B)

The temperature at which a liquid converts to gas at vapor pressure equal to atmospheric pressure is known as the boiling point. At this temperature, the molecules within the liquid have enough energy to overcome intermolecular forces and transition into the gaseous state. This process occurs uniformly throughout the liquid, as opposed to a flash point, which refers to the temperature at which vapors can ignite but the liquid does not completely vaporize. The fire point is similar but indicates the lowest temperature at which the vapors will continue to burn. Freezing point, on the other hand, is the temperature at which a liquid solidifies. Therefore, the definition of boiling point aligns perfectly with the context of the question regarding phase change at atmospheric pressure.
