Q

The effective temperature of air is dependent upon what factor or factors? relative humidity air velocity

🔍 Key Concepts

• Effective temperature as a measure of how hot/cold air feels to a person, not just the thermometer reading • How relative humidity changes the body’s ability to cool by sweating • How air velocity (wind speed) affects heat loss or gain from the body

💭 Think About

• Think about standing in a room at the same dry-bulb temperature: how does it feel when the humidity is very high versus very low? • At that same temperature, how does it feel when the air is still versus when a fan or wind is blowing? • Which of these factors actually change your sensation of warmth or coolness at the same measured temperature?

✅ Before You Answer

• Verify whether effective temperature is defined as a comfort index that combines dry-bulb temperature with humidity and/or air movement • Check how high humidity at a given temperature affects evaporative cooling from sweating • Check how increased air velocity (like a fan or wind) affects convective heat loss from the body at the same temperature
