Question

количество водяного пара в воздухе равна 2 г при температуре 0 градусов найти относительную влажность​

Answer 1

40,8%

Абсолютная влажность на 0 градусов = 4,9 (после округления до десятых)

2/4,9×100%=40,8%

Answer 2

Calculation of Relative Humidity

To calculate the relative humidity, we need to know the actual vapor pressure and the saturation vapor pressure at the given temperature. The formula for relative humidity is:

Relative Humidity = (Actual Vapor Pressure / Saturation Vapor Pressure) * 100%

Given that the amount of water vapor in the air is 2 g at a temperature of 0 degrees Celsius, we can use this information to calculate the relative humidity.

Actual Vapor Pressure

The actual vapor pressure represents the pressure exerted by the water vapor in the air. In this case, the actual vapor pressure is 2 g.

Saturation Vapor Pressure

The saturation vapor pressure represents the maximum amount of water vapor that can be present in the air at a given temperature. To find the saturation vapor pressure at 0 degrees Celsius, we can refer to the following source:

According to the source, at 0 degrees Celsius, the saturation vapor pressure is approximately 0.01% to 0.2%. Let's assume an average value of 0.1%.

Calculation

Using the values we have:

Actual Vapor Pressure = 2 g Saturation Vapor Pressure = 0.1% of the maximum saturation vapor pressure at 0 degrees Celsius

We can now calculate the relative humidity:

Relative Humidity = (2 g / 0.1% of the maximum saturation vapor pressure at 0 degrees Celsius) * 100%

Please note that the specific value for the saturation vapor pressure at 0 degrees Celsius is not provided in the search results. However, we can assume an average value of 0.1% based on the information provided.
