Answer 2

Partial Pressure of Vapor and Relative Humidity

To find the relative humidity and the amount of condensation that occurs when the temperature is cooled to 3°C, we need to understand the concepts of partial pressure of vapor and saturation vapor pressure.

The partial pressure of vapor is the pressure exerted by the water vapor in a mixture of gases. It is a component of the total pressure of the gas mixture. The saturation vapor pressure is the maximum pressure that water vapor can exert at a given temperature. When the partial pressure of vapor equals the saturation vapor pressure, the air is said to be saturated.

In this case, the partial pressure of the vapor at the given temperature is 1.6 kPa, and the saturation vapor pressure at the same temperature is 2 kPa.

Finding Relative Humidity

The relative humidity (RH) is the ratio of the partial pressure of vapor to the saturation vapor pressure, expressed as a percentage. It can be calculated using the formula:

RH = (partial pressure of vapor / saturation vapor pressure) * 100

Let's calculate the relative humidity for the given values:

RH = (1.6 kPa / 2 kPa) * 100 = 80%

Therefore, the relative humidity is 80%.

Amount of Condensation

To find the amount of condensation that occurs when the temperature is cooled to 3°C, we need to compare the saturation vapor pressure at 3°C with the partial pressure of vapor at the initial temperature.

Unfortunately, the saturation vapor pressure at 3°C is not provided. Without this information, we cannot accurately determine the amount of condensation that will occur.
