Heat transfer
Текст Раскадровки
- Introduction
- Joule, that is why we are talking about heat the humidity is sky rocketing.
- Today in the cool kids club are taking about heat.
- Talking about heat it is totally hot out here
- Radiation
- Hay viewer if you haven't clued in, radiation is how you feel heat through places with out molecules like outer space radiation also travels through waves.
- See the sun is still up it is 7:00. the earth is getting way more radiation than need
- Convection
- Convection is how heat transfer through liquids and gases o the screen you should see some arrows on how convection works
- We have just moved to below sea level to tell you about convection an man it feels gust a bit colder
- Noah: We will split-up into two teams me and lily and Matthew and Joule. Lily: My team will cover radiation and your team will cove convection then meat back here. All: let's go.
- Conduction
- Together: Hot, ouch why are their a hot metal poles under us!
- Together: There is are example of conduction. Conduction is heat transferring directly to its disiared location.
- Lily: So radiation is how heat transfers from places with no molecules are sun is a big provider of radiation. Noah: Your right are sun provides heat through radiation it radiates all 8 planets radiation also describes how you feel warm 1 yard away from a fire.
- Heat Transfer
- Finally heat transfer do any of you no what it means?
- I do heat transfer is what we have been talking about. Heat transfers from a warm object to a cool object in the three ways we talked about.
- Matthew: The arrows so how the heat rises and the cold air sinks. Joule: Sense we are lower the air is cold and the upper air is warm like a house on fire smoke goes to the top and the air goes down.
- Conclusion
- In conclusion heat transfer happens all around you every day for us it was just a harsh weather
- The boys: Now that was unfair, you know we weren't prepared. Lily how else were we supposed to show conduction. Noah: Well we could have staned on radiated sand. Matthew Or we could have stuck metal poles into fire. Joule: I guess you were right we're sorry for what happened.
- Lily: So Joule you mean that all the ways we said het moves how heat transfers? Joule: Yes heat transfer is how heat moves but do remember it heat moves from objects with a lot of heat to objects with no less heat.
- Oh thanks Joule.
- All: Thats a wrap!
- For us the cool kids club is now stuck inside do to rain cement on what you want us to tell you about next.
