This post was last edited by Cuaili Yisu on 2016-1-12 08:46. Brief question: What is the dew point temperature? It is the pressure at which a compressed gas mixture begins to condense and the first liquid droplets appear, under constant temperature conditions. Correct answer = +2; in-depth discussion = +5 @ Guan Gongyu

What is dew point temperature? It refers to the temperature at which air reaches saturation when its water vapor content and pressure remain unchanged. Put simply, the temperature at which water vapor in the air turns into dew drops is called the dew point temperature

Dew point temperature refers to the temperature at which air reaches saturation when its water vapor content and pressure remain unchanged. Put simply, the temperature at which water vapor in the air turns into dew drops is called the dew point temperature. When the water vapor in the air is saturated, the air temperature is equal to the dew point temperature ; When the water vapor is not saturated, the air temperature must be higher than the dew point temperature. Therefore, the difference between the dew point and the air temperature can indicate the degree to which the water vapor in the air is close to saturation.

Dew point (or frost point) temperature: dew temperature. Dew point temperature refers to the temperature at which air reaches saturation when its water vapor content and pressure remain unchanged. Put simply, the temperature at which water vapor in the air turns into dew drops is called the dew point temperature. The dew point temperature is originally a temperature value, so why is it used to represent humidity? This is because when the water vapor in the air reaches saturation, the air temperature is equal to the dew point temperature ; When the water vapor is not saturated, the air temperature must be higher than the dew point temperature. Therefore, the difference between the dew point and the air temperature can indicate the degree to which the water vapor in the air is close to saturation. A temperature dropping below the dew point is a necessary condition for water vapor to condense.

At 100% relative humidity, the temperature of the surrounding environment is the dew point temperature. The lower the dew point temperature compared to the temperature of the surrounding environment, the less likely condensation will occur. This means that the air is drier. The dew point is not affected by temperature, but rather by pressure.

Dew point temperature 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 temperature.

This is because when the water vapor in the air reaches saturation, the air temperature is equal to the dew point temperature ; When the water vapor is not saturated, the air temperature must be higher than the dew point temperature.

The dew point is not affected by temperature, but rather by pressure. The wet-bulb temperature is defined as the adiabatic saturation temperature reached when air is in direct contact with water under constant-pressure adiabatic conditions, at which a stable heat and moisture balance is attained.
