Help please anyone?
If the wet-bulb thermometer and the dry-bulb thermometer readthe same temperature, the air is said to be???
Anyone know?
Yes, I can help you with that question. When the wet-bulb thermometer and the dry-bulb thermometer read the same temperature, the air is said to be in a state of saturation or at the dew point.
To understand why this is the case, we need to know a bit about how these thermometers work. The dry-bulb thermometer measures the ambient air temperature, while the wet-bulb thermometer is fitted with a wet wick around its bulb. When air is passed over the wet-bulb, the moisture on the wick evaporates, causing the temperature of the bulb to drop.
In normal conditions, the wet-bulb temperature will be lower than the dry-bulb temperature because evaporation causes cooling. However, when the air is saturated with moisture, meaning it is holding the maximum amount of moisture it can at that temperature, evaporation is very limited. As a result, the wet-bulb and dry-bulb thermometers will read the same temperature.
This state of saturation or reaching the dew point is an important concept in meteorology and indicates that the air is fully saturated with water vapor.
