Question

определить относительную влажность воздуха, если при температуре +30о С в нём содержится 18г водяного пара.)

Answer 1

Ответ:

(18 * 100) : 30 = 60 (г) - влажность воздуха .

Ответ : влажность воздуха 60 градусов .

Объяснение:

Для того чтобы определить относительную влажность нужно 18г водяного пара умножить на 100 , а затем разделить на +30о градусов .

Answer 2

Calculating Relative Humidity at 30°C with 18g of Water Vapor

To determine the relative humidity at a temperature of 30°C with 18g of water vapor, we can use the formula for relative humidity:

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

First, we need to calculate the actual water vapor pressure and the saturation water vapor pressure at 30°C.

Calculating Actual Water Vapor Pressure

The actual water vapor pressure can be calculated using the following formula:

Actual Water Vapor Pressure = (Mass of Water Vapor / Molecular Weight of Water) × (Universal Gas Constant) × (Temperature in Kelvin)

Given: - Mass of water vapor = 18g - Molecular Weight of Water = 18g/mol - Universal Gas Constant = 8.314 J/(mol·K) - Temperature = 30°C = 303.15K

Using these values, we can calculate the actual water vapor pressure.

Calculating Saturation Water Vapor Pressure

The saturation water vapor pressure at 30°C can be obtained from the Antoine equation or from a table of vapor pressure values for water at different temperatures.

Using the saturation water vapor pressure at 30°C, we can then calculate the relative humidity using the formula mentioned earlier.

Let's proceed with the calculations.

Calculations

Actual Water Vapor Pressure: Actual Water Vapor Pressure = (18g / 18g/mol) × (8.314 J/(mol·K)) × (303.15K)

Saturation Water Vapor Pressure: The saturation water vapor pressure at 30°C needs to be obtained from a reliable source or calculated using the Antoine equation.

Relative Humidity: Relative Humidity = (Actual Water Vapor Pressure / Saturation Water Vapor Pressure) × 100%

By plugging in the calculated values, we can determine the relative humidity at 30°C with 18g of water vapor.
