AHH FREEZING WINTER! I'm glad I have Heat...

Heyo! I'm back! If you don't want me here... Well too bad! Haha anyway, this week we are talking about - Man its cold in here! I'm glad we have- HEAT! Heat is a simple but effective concept to learn about. It’s simple, and heat affects you when you’re cold! Like I am right now, freezing cold! Heat is the transfer of thermal energy from one object to another when the objects are at different temperatures. Obviously, I love heat because I am always cold. BRR!

Heat is an interesting thing. It can be transferred in three different ways. The first way is Conduction. Conduction occurs when the particles in a material collide with neighboring particles. Basically, conduction happens when two objects with different temperatures, one being hot, touch, the heat transfers from one to another. Not to hard, right? An example of conduction is when you put a pot on the stove. The stove has heat from the small flame is producing. When the flame's particles touch the bottom of the pot, the heat transfers from the flame to the metal pot. This is the first out of three ways to learn. :D

Conduction isn't the only way to transfer heat, another way is called Convection. Convection is the transfer of heat by the movement of atoms or molecules from one part of a material to another. Another way of saying that is convection occurs when there is heat source on the bottom, and it makes the air warmer and it rises. When it rises, the cooler air on the top goes down. Then when it heats up again, it pushes the used-to-be warm air down because it is now cold. The cycle goes on repeat after that unless the hear source it taken away. It sounds confusing, but it really isn't. An example of it is when you put water in the pot that was warming p from the stovetop flame. The bottom part of the pan will heat the water on the bottom. Then, the warmer water rises, while the cooler sinks. Then the cooler water turns warm, and pushes the used-to-be warm water down to the bottom. Like I said, the process repeats continuously. One more to go! :D

The third and final way to transfer heat is called Radiation. Radiation is the transfer of energy in the form of electromagnetic waves. In other words, Radiation is one of the ways to transfer heat; it transfers by electromagnetic waves. A couple examples of Radiation are the sun, fire, and many more. Sorry, I can't use the water in a pot example this time. The way the sun transfers heat is by it's waves that travel down to Earth and heat up the planet. If the sun weren’t there, this planet would be a freezing cold planet. There you go, those are the three types of how to transfer heat! 

Now, there are a couple more things we need to talk about. Firstly, we shall talk about conductors. Conductors are materials or objects that allow energy to flow through them. A good example or a conductor is metal. Any types of metal, like iron, gold, nickel, and many more. Metal is a great conductor because it is easily heated. Things like plastic foam, feathers, and fur aren't because the material doesn't observe heat or let heat through the material. This is why blankets keep you warm! It doesn't let your body heat through, so it stays and keeps all of the heat around your skin. That sounds weird… Oh well. 

Question time! In order to heat a room evenly, should heating vents replaced near the floor or near the ceiling of the room? What do you think? Would you pick the ceiling or the floor? I think the floor because then it would make the warmer air rise making the cooler airdrop thus making convection current! Interesting, right?! I have three interesting facts for you! The lowest temperature you can go is approximately -273 degrees Celsius, also known as absolute zero. Right after the Big Bang, the temperature was so hot that it couldn't even form molecules. Now this is seriously random. When the temperature reaches 95 degrees, the human work output drops 45%. Weird, right? Well, I'll see ya next week! Byyyee!

just typing it! Tell me your feedback please!
 I would love to know what you thought of this! 
Thanks for reading everyone! <3
