🔍 Key Concepts

• Density of air and how water vapor affects it • Difference between absolute humidity and relative humidity • How temperature affects the air’s capacity to hold water vapor

💭 Think About

• Compare the molecular weights of dry air’s main gases (like nitrogen and oxygen) with water vapor. What happens to overall density when more water vapor is mixed in? • Think about what happens to the maximum amount of water vapor air can hold as temperature increases: does warm air or cold air hold more moisture? • If you take a fixed sample of air and heat it without adding or removing water vapor, what happens to its relative humidity: does it go up or down?

✅ Before You Answer

• Be clear on the difference between moist air vs. dry air density under the same temperature and pressure. • Verify how warmer air’s moisture capacity compares to colder air’s. • Remember that relative humidity is a ratio: actual moisture content divided by the maximum the air could hold at that temperature. Consider how that ratio changes when temperature alone increases.
