Why do you think hot air rises? Hot air rises because it would be warn, and with that it would be less dense. Also, the hot substance will evaporate,
Conclusion Questions:
1. What is conduction and how was it simulated in the lab?
Conduction is when heat is tranfered by a physical transformation. This is simulated in the lab when the fire touches the tea bag, and transfers the heat to the tea bag. With that, it catches on fire.
2. What is convection and how was it simulated in the lab?
Convection is when warmer air rises because of the density. This is shown by the tea bag that's on fire rising up into the air.
3. Is hot or cold air denser and how does the density of air affect its motion?
Cold air would be denser, and the density of air affects the motion since hot air will always rise.
4. Describe how conduction and convection work together when you are heating soup on the stove?
The fire from the stove will get to the pot, which is then transfered to the soup. That would represent conduction. Convection is represented by smoke rising since the soup would get hot.
5. Now that you hopefully know why hot air rises, what would be the best way to escape a burning building?
The best way to escape would be from the bottom of the building, since the heat rises.
