heat transfer, density, air pressure,electromagnetic spectrum
| Question | Answer |
|---|---|
| How does the density of air change as air is heated of cooled? | The density changes by decreasing if it is warm and increasing if it is cooled. |
| How are density and air pressure related? | They are related because the both do with the amount of air. |
| What 2 things can change the density and pressure of air? | The two things that can affect the density and presure are temprature and altitude. |
| How does heating and cooling affect the movement of air? | It affects it becuase when it is warm the air moves quicker and it is less dense, and when the air cools it becomes more dense and it will move slower. |
| how does land and water heat and cool? | Water will heat up slower and cool slower. Soil will heat up faster and cool faster. |
| When a surface is hot how does the air aroung it change? | The air around it uses condustion and heats up, then heats up the other air using convection. |
| if you are at the beach during the day what will be hotter? sand or water? | If you are at the beach durng the day the sand will be warmer then the water. |
| What is albedo? | The amount of light reflected. |
