Learn from the advanced practices of the *Brothers section; there are rewards for correct answers – every response earns a reward, allowing us to grow and mature through these Q&A sessions. Short answer: What is dew point? What is the bubble point? What is the boiling point?
The gas mixture is cooled at constant pressure; when it reaches a certain temperature, the first tiny droplets form. This temperature is known as the dew point of the mixture at that specified pressure. Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure. Boiling point: The temperature at which, under a certain pressure, the saturated vapor pressure of a substance is equal to that pressure.

Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure. Boiling point: The temperature at which, under a certain pressure, the saturated vapor pressure of a substance is equal to that pressure.
Dew point refers to the temperature at which air humidity reaches saturation; when the water vapor in the air is saturated, the air temperature is equal to the dew point； When the water vapor is not saturated, the temperature must be higher than the dew point temperature. Bubble point: at a constant temperature, it is the pressure at which the first bubbles begin to separate from the liquid phase; or, at a constant pressure, it is the temperature at which the first bubbles begin to separate from the liquid phase. The boiling point is the temperature at which the saturated vapor pressure of a liquid equals the external pressure; it is the boiling point of the liquid under that pressure.
The dew point is the temperature at which the first droplets begin to separate from the gas phase under a constant pressure. Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure.

Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure. Dew point: A gas mixture is cooled at constant pressure; when it is cooled to a certain temperature, the first tiny liquid droplets appear, and this temperature is known as the dew point of that mixture at the specified pressure.

Dew point: When a gas mixture is cooled at constant pressure, a certain temperature is reached at which the first tiny liquid droplets appear; this temperature is known as the dew point of that mixture at the specified pressure. Bubble point: The pressure at which the first bubbles begin to form in the liquid phase, or the temperature at which the first bubbles begin to form in the liquid phase, under constant temperature conditions. Boiling point: The temperature at which, under a certain pressure, the saturated vapor pressure of a substance is equal to that pressure.
Boiling point: The temperature at which, under a certain pressure, the saturated vapor pressure of a substance is equal to that pressure. Saturated vapor pressure: The pressure of the vapor that is in phase equilibrium with a liquid or solid at a certain temperature is called the saturated vapor pressure. Boiling is a violent vaporization process that occurs simultaneously inside and on the surface of a liquid at a certain temperature. The temperature at which a liquid boils is called the boiling point. The higher the concentration, the higher the boiling point. Different liquids have different boiling points; the boiling point refers to the temperature at which different liquid substances boil. The boiling point changes with external pressure; lower pressure results in a lower boiling point. Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure. Dew point refers to the temperature at which air becomes saturated when cooled, with neither its water vapor content nor pressure changing. Put simply, the temperature at which water vapor in the air turns into dew drops is called the dew point.
The dew point is the temperature at which the first droplets begin to separate from the gas phase under a constant pressure. Bubble point: The pressure at which the first bubbles begin to separate from the liquid phase at a constant temperature, or the temperature at which the first bubbles begin to separate from the liquid phase at a constant pressure. Boiling point: The temperature at which, under a certain pressure, the saturated vapor pressure of a substance is equal to that pressure.
