Answer 1

Ответ:

Объяснение:

делим плотность пара (абсолютная влажность) на плотность насыщенного пара и умножаем на 100%

8 /20,6=38.8%

Answer 2

Calculation of Relative Humidity

To determine the relative humidity of the air, we need to compare the actual amount of water vapor present in the air (absolute humidity) to the maximum amount of water vapor the air can hold at that temperature (saturation point).

Given: - Temperature: 23 °C - Absolute humidity: 8 g/m³ - Density of saturated air: 20.6 g/m³

To calculate the relative humidity, we can use the formula:

Relative Humidity = (Absolute Humidity / Saturation Point) * 100

First, let's calculate the saturation point of the air at 23 °C using the given density of saturated air.

Saturation Point = Density of Saturated Air / Density of Water Vapor

Using the given density of saturated air (20.6 g/m³) and assuming the density of water vapor is 1 g/m³, we can calculate the saturation point:

Saturation Point = 20.6 g/m³ / 1 g/m³ = 20.6

Now, we can calculate the relative humidity:

Relative Humidity = (8 g/m³ / 20.6) * 100 ≈ 38.8%

Therefore, the approximate relative humidity of the air in the physics lab at a temperature of 23 °C and an absolute humidity of 8 g/m³ is 38.8%.

Please note that the calculation assumes the density of water vapor is 1 g/m³, which is a common approximation. The actual density of water vapor can vary slightly depending on temperature and pressure.
