This topic is on the states of matter involving the earth. We learned that what happens a lot is that the core of the earth is the hottest layer of the earth because it has the most pressure causing very hot temperature due to the friction. Then as the layers get farther away from the core the cooler it is because of less pressure causing less heat/ temperature. So what we learned was that temperature and pressure cause things in the earth to change. Such as when the plates come together it causes the plates to push up creating mountains and another example that then when the plates pull apart it opens up the earth creating volcanos letting lava out because the inner layers get exposed. Or when we created rocks the chemical reaction caused pressure inside making atoms to come together and create the rock, I believe.
Inner core: Iron and Nickel creating a solid
Outer core: Iron and Nickel creating a liquid
Mantle: Thick, mostly silicates.. 97% (SiO3)-2
Crust: Solid silicates

Dry ice:
We did an experiment with dry ice, such as putting a coin on top of the ice or putting the ice into water and the most crazy one was Andrew had the dry ice into a pressurized tube and then shot it off. When we had put the ice into the water it caused moisture/ fog. I feel this is caused because of the cold ice goes into somethings warmer than it causing the temperature to change in the ice making it less dense and being able to turn into a gas which we call fog or moisture. What we had done next was put coins onto the ice. The coins began to be covered by the ice. I think this happened because the coins were warmer than the ice also causing what was left under the coin started to melt and began to then try to make the coin just as cold as it, and it began to start freezing the coin. When Andrew had put the ice into the pressurized tube it turned into water when it got to 70-80PSI. I believe this is because when the water shot out of the tube the temperature and pressure change caused the water to freeze again creating snow.
So what we talked about today was pressure, density and
buoyancy. Density = mass/ volume and when you change
the volume it changes the density causing it to be heavier
to lighter than something like air or water. If you had wood
and put it in water it tends to float, and say you were to drop
a marble in water. The wood will float and the marble will
sink because the density in the two objects are different and
water is somewhere between the to. Meaning that the density
of water is less than a marble and more than wood. So my hypothesis is if you take volume and change it causing more buoyancy it is the cause for things to float. Just like what we did to the balloons with candles today.
