Question

задача помогите решить пожалуйста!! комната имеет 170м3. определить сколько влаги содержится в воздухе при температуре +20 градусов и влажности 50%. сколько влаги выделится, если открыть окно до температуры 0 градусов

Answer 1

я не знаю как учитывать влажность 50%, взяла вообще информацию из физики про абсолютную влажность.

Абсолютная влажность воздуха  — это количество водяного пара, содержащегося в 1 м³ воздуха. и такая табличка:(см. вложение)

 

ну если смотреть по ней, то при +20  влажность - 17,3*170=2941

а при 0 - 4,8*170=816

наверное это не правильно!

 

Answer 2

Problem Analysis

To solve this problem, we need to determine the amount of moisture present in the air in a room with a volume of 170 m^3 at a temperature of 20 degrees Celsius and a humidity of 50%. We also need to calculate the amount of moisture that will be released if the window is opened and the temperature drops to 0 degrees Celsius.

Solution

To find the amount of moisture present in the air at 20 degrees Celsius and 50% humidity, we can use the formula:

Moisture content = Volume * Humidity / 100

Substituting the given values, we get:

Moisture content at 20 degrees Celsius and 50% humidity = 170 * 50 / 100 = 85 m^3

Therefore, there is 85 m^3 of moisture present in the air at 20 degrees Celsius and 50% humidity.

To calculate the amount of moisture that will be released when the window is opened and the temperature drops to 0 degrees Celsius, we need to consider the change in temperature and the resulting change in the moisture-holding capacity of the air.

As the temperature decreases, the air's ability to hold moisture decreases. To calculate the new moisture content, we can use the formula:

New moisture content = Old moisture content * (New temperature / Old temperature)

Substituting the given values, we get:

New moisture content = 85 * (0 / 20) = 0 m^3

Therefore, if the window is opened and the temperature drops to 0 degrees Celsius, all the moisture in the air will be released, resulting in 0 m^3 of moisture remaining.

Conclusion

In conclusion, the room initially contains 85 m^3 of moisture at a temperature of 20 degrees Celsius and 50% humidity. If the window is opened and the temperature drops to 0 degrees Celsius, all the moisture will be released, resulting in 0 m^3 of moisture remaining in the air.
