You do not talk about energy

Howdy, everyone! Once again we shall be addressing quite an important and diverse subject. No, we sadly aren't delving into the deliciously complicated psyche of Robert James Smith; we're talkin' about the concept of energy. Energy is pretty difficult do describe. It's sort of like being asked what water tastes like; water! However, if I had to explain then I'd say this: energy is the ability to cause some action to occur. Energy can be transferred or stored. It can't be created or destroyed. Again we are dealing with a megalithic concept here with magnitudes of content inside it. Right now we're only worrying about Potential and Kinetic energy.

Both Potential and Kinetic energy pertain to movement; motion. Potential energy is the energy a thing will have due to it's placement. A super generic example would be a pebble perched precariously on an ant-hill. Now let's say that pebble is a boulder and the ant-hill it was on is now a mountain! The boulder on the mountain has more potential energy than the pebble on an ant-hill. That's because the higher an object is and the more mass it has, the more Potential energy.

 Kinetic energy is the energy that a moving object has. The more speed and mass an object has the more kinetic energy. If the pebble begins to roll down the anthill it will have less energy than if the boulder rolls down the mountain. That's because again when something has more mass the more kinetic energy it will have.

Also, kinetic energy can be transferred from one object to another. It's against the rules to talk about this ,but it's a fantastic example. Let's say you're in Fight club, right? Okay, so you're Tyler Durden, and all of your bros are circling you and this other guy. That's because you and he are about to engage in an epic rumble of bro-ness. You, being Tyler Durden, punch this fella and, Wham, down goes Frazier! When you, Tyler Durden, punched that guy's face you were transferring energy. Also, pain, but mostly energy. Quite a lot of energy too!

That's about all, folks! please leave all comments, milkshakes, Simon Gallups, Robert Smiths, and puppies down bellow. All information from notes in class and probably Brainpop.

It doesn't Matter

     Howdy, everyone! Today we’ll be talking about something that matters a whole lot; matter! Seriously, though matter is insanely important. Even more important than that Cure album I’ve been wanting; yeah that’s pretty dog garn important! Matter is everything under the sun; it even is the sun. That’s because matter is anything that takes up space. Matter is you, me, cheeseburgers, Brad Pitt, India, computers, Mars, budgies, Budgie, the moon, the Disintegration album, nail polish, Wisconsin; you get the idea.  In case you hadn’t figured out by now, matter is a huge multi-faceted concept, so we’ll be taking it on little by little. First, let’s learn about how matter changes states.

      There are three states of matter: solids, liquids, and gases. Matter changes states when exposed to pressure and temperature changes. I'd like to mention that no matter what state of matter a substance is in, it will retain it's chemical properties. Sort of like how when you wear a super cute outfit and curl your hair one day, but then the next day you just wear sweats and a ponytail. You're still you, only your physical appearance changed.

      First, let’s talk about solids. Solid is the state of matter where the molecules within something are tightly packed together. Solids have a definite shape and volume under normal conditions. A good example of a solid would be ice.
      Next let's talk liquids. Liquids have a fixed volume, but not a fixed shape. The molecules inside liquids are fluid, just like liquids themselves! An obvious example of liquids would of course be water. Solids become liquids after reaching a melting point. Ice's melting point is 32 degrees. This also bleeds into heat of fusion. Heat of fusion is all energy being put towards melting something. If you were to be boiling a bunch of ice and put a thermometer in it, the heat will not rise until all the ice has melted. Neat, huh?
      Finally, we have the gas state. In the gas state molecules within the gas will move around randomly and wildly. Gases have no fixed shape or volume. A good example of a gas would be water vapor. I should also mention Heat of Vaporization. It's a lot like Heat of Fusion, only this is where all energy is spent turning something into a gas. Again, if we I were to boil water, the temperature would remain the same until the water has evaporated.
      Those aren't really the only three; they're just the main ones. There are still Colloids and Plasmas which I'll go into briefly. Plasmas are electrically charged gases, like stars and lightning.

 Colloids are a mixture that contains two different phases of matter. An example would be pudding, milkshakes, yogurt, smoothies, dang it I'm hungry now!

      Finally, let's talk about Condensation, Sublimation, and Deposition. Condensation is the process of a gas turning into a liquid. Ever leave a water bottle out on a hot day? Notice all those water droplets covering the inside? That's from condensation. Next we have Sublimation; a gas turning into a solid. An example of this would be Carbon Dioxide into Dry Ice. Speaking of dry ice; that's where all that awesome fog comes from during Iron Maiden Performances! Finally we have Deposition. Deposition is the concept of gas changing to a solid. That's what causes frost patterns on your windows in the winter!

     Well, I think that's all that matters. Sorry about that one; I hope this helped you guys out! Leave I comment or else I will drink your milkshake. Actually, I'd drink your milkshakes whether you comment or not.
