As the amount of moisture in the air increases, what will happen to the difference between the dry bulb and wet bulb temperatures?

🔍 Key Concepts

• Relative humidity and how it relates to moisture content in the air • What the dry bulb thermometer measures vs. what the wet bulb thermometer measures • What happens to evaporation from the wet bulb as the air gets more humid

💭 Think About

• Think about how evaporation from the wet bulb thermometer changes when the air is already holding a lot of moisture versus when it is very dry. • If evaporation from the wet bulb slows down, what happens to the wet bulb temperature compared to the dry bulb temperature? • At 100% relative humidity (air fully saturated), what do you expect the dry bulb and wet bulb readings to look like in relation to each other?

✅ Before You Answer

• Be clear on the definition of relative humidity = how full of water vapor the air is, compared to the maximum it can hold. • Review that wet bulb temperature is lowered by evaporation, and evaporation is stronger in drier air. • Mentally compare: very dry air vs. nearly saturated air – in which case would the difference between dry and wet bulb readings be larger?
