Phases of Matter putting it all together. Pg. 70L

What happens to the density of air as it is warmed and cooled? As air gains thermal energy it becomes less dense as it loses thermal energy it becomes more dense.

2. How does the density of air affect if air rises or sinks? Warm air is less dense and rises because it is lighter than the surrounding air. Cold Air is more dense and sinks because it is heavier than the surrounding air.

4. What happens to the temperature of the air as you rise higher into the atmosphere? Temperature decreases as you rise higher into the air. The further you get from the earth the colder it gets.

5. Draw a model!
