Problem: How does convention move air?
Hot air rises because it is not as dense as the cooler air
Hot air rises because it is not as dense as the cooler air
The column of the tea bag before we have done anything
After we lit the column, the column got so light that the cold air was able to push up the burnt column with the hot air.
Conclusion Questions:
1. What is conduction and how was it simulated in the lab? Conduction is the transfer of heat energy through touch. It was shown in the lab because the heat energy from the match was transferred to the column made of a tea bag.
2. What is convection and how was it simulated in the lab? Convention is the circulation of fluids. It was shown in the lab because the column of the tea bag was forced into the air by the cooler air after it was burnt.
3.Is hot or cold air denser and how does the density of the air affect its motion? Cold air is denser than warm air. The density of the air affects its motion because the cooler air pushes up on the warmer air.
4. Describe how conduction and convection work together when you are heating soup on the stove? Conduction is when the pot touches the soup and heats the soup up. Convection happens when the hot steam rises up from the soup or when you stir the soup.
5. What would be the best way to escape a burning building? To crawl towards the exit under all of the smoke and ash
