Question 1 of 27070

In air has 100% relative humidity, how would the wet bulb temperature relate to the dry bulb temperature?

🔍 Key Concepts

• Relative humidity (RH) and what 100% RH physically means • How a psychrometer (wet bulb and dry bulb thermometer) works • The role of evaporation and cooling on the wet bulb temperature

💭 Think About

• If the air is already holding as much water vapor as it can (100% RH), what happens to evaporation from the wet bulb? • In normal (less than 100% RH) conditions, is the wet bulb usually higher, lower, or the same as the dry bulb—and why? • At the exact point of saturation, how would the temperatures of the two thermometers compare if there is no net evaporation or condensation at the wet bulb?

✅ Before You Answer

• Be clear on the definition of 100% relative humidity (air is saturated). • Decide whether evaporative cooling can still occur at 100% RH. • Remember that the wet bulb temperature is the lowest temperature reachable by evaporation alone. At saturation, verify how this limit relates to the dry bulb temperature.
