thermal expansion
Texte du Storyboard
- yeah! Thermal expansion is where molecules change based on the temperture. ill show you an example. lets walk to the busses and ill show you in the mean time i can tell you more
- my teacher was telling me about thermal expansion and i was super confused do you know what it is?
- i am going to show you what happens with a bus tire. but in the mean time i can tell you what happens to the material in it. so basicly what happens is that the volume goes down in the tire because of the molecules spreading out. i will tell you what happens with the molecules once we get there.
- ok cool this is very nice of you to explain
- its so cold. and the bus cant move because of the thermal expansion.the buses tire is flat. this happens because when something is cold all the molecules become pact to gather and it then seems that there is no air even though it just got filled yesterday. when something is warm all the molecules spread out. and because it was warm yesterday this is why it is happening
- wow that is so cool thanks for teaching me all about it! i now understand it!
