In these first two chapters, we have been discussing temperature and heat, with special attention to heat exchange and the ways in which gaining or losing heat can affect a material.
- Think up a way in which heat/phase changes exist in the practical world. This can be a man made or completely naturally occurring event.
- Some examples to get the brains going (you can pick one of these, but creativity is encouraged!): How does sweat cool us down? What causes wind or weather events like tornados/hurricanes/snow/rain/hail? Why/how do we use heat to create most of our electrical power? How does your gas/electric stove cook food? How do we create 3D prints of materials using thermal energy? How does the air conditioning in your house work? Is there a more efficient way to cool your refrigerator that got wiped out decades ago by big electricity? How do we use heat to do work? Do temperature and heat cause waves in the ocean? How does it aid in making fried treats in an air fryer? etc.
- Once you have your topic, briefly research that example and then reply here including the following:
- What the example is.
- What type of heat exchange/ phase change is occurring.
- Where/ how is that heat exchange/ phase change occurring.
- A brief description of how that heat exchange/ phase change causes or drives your example.
- This initial reply is worth 5 points.
- Reply to at least one other student to discuss their example.
- Please pick a post on a different example than the one you chose.
- Describe how you have experienced that process yourself, or try to imagine a way in which their example can be used or useful in general.
- Basically just try to expand on their post and add to it, with a focus on the physics of it.
- This second reply is worth 5 points.
