Hello People! Sorry I haven’t posted in a while; my schedule has been really
crazy. Anyway, lets learn some more about science! I have a quiz on Thursday,
and I need to study for it. While I am studying, you will be learning! Yay! :D
We are going to learn about matter and what happens when it changes states.
First, you will need to know some of the basics. Matter is anything that takes
up space. Some examples being paper, carrot juice, and even carbon dioxide! I
know, pretty random, but they are all made of matter. Paper, carrot juice, and
carbon dioxide are examples of the three basic states of matter. The three
basic states of matter are solids (paper), liquids (carrot juice), and gasses
(carbon dioxide). All three states are completely different, but extremely
similar at the same time. Confusing, I know, but you will get it in a second.
I’m going to use water (I know, everyone uses
this, it’s just the easiest to understand) as an example. We are going to start
with ice. Ice is a solid. A solid is a state of matter where the particles are
bonded together in a lattice structure. If you were to give energy to it, like
melting it, you would get water. Water is a liquid. A liquid is a state of
matter that contains energy, but only enough for the particles to move around a
little freely. If you were to take even MORE energy from water, like
vaporization, you would get water vapor. Water vapor is a gas. A gas is a state
of matter that has so much energy, that the particles move around randomly.
It’s pretty weird, but cool, right?
Okay, now that you know the basics, I’m going to
study a little more in depth about the changes. In order to take away and give
energy, you would need to either change the temperature or apply/take away
pressure. For the temperature changes, if you wanted a solid, like ice, you
would need to have it frozen at either 32ᵒF or 0ᵒC. Its molecules are bonded
and packed together in a structure called a crystal lattice. From that
temperature and down, it will freeze.
When you melt ice, the temperature of it changes
to its melting point. The temperature stays the same until all the ice melts.
After that is when the temperature starts to grow again. When that is
happening, all of the energy is used to breaking the bonds of the ice
molecules. The extra energy is called the heat of fusion. The melting point of
water is when the temperature is above 32ᵒF or 0ᵒC. That melting point is only
for water, though. The melting point is interesting. Each element or compound
has its own melting point. Water is at 32ᵒF or 0ᵒC, and another element, like Magnesium,
has a melting point of 1200ᵒF or 600ᵒC.
If you wanted water in a gas form, you
will obviously need to do something about it. You would need to
add enough energy or heat to break the forces of attraction of the molecules.
That energy that is being used is called the heat of vaporization. The boiling
point of the water to turn it into a gas is 212ᵒF or 100ᵒC. These are the ways
to change states by temperature, but there still is pressure. If you want to
get it from a solid to a liquid or a liquid to a gas, you would need to ADD
pressure. If you wanted to get it from a gas to a liquid or a liquid to a
solid, you would need to TAKE AWAY pressure. When you do this, the chemical
properties will stay the same.
Not all substances change from one to another.
Some substances skip a process, like going straight from a solid to a gas. This
process is called sublimation. One example of sublimation is dry ice. Dry ice
is frozen carbon dioxide. So, when it sublimates, it goes from dry ice to
carbon dioxide. Pretty cool, huh? Another way is when it goes from a gas
straight to a solid. That is called deposition. An example of that is dry ice, once again. When carbon
dioxide freezes, it turns into dry ice. One last way is called condensation.
That’s when a gas form of something changes back into a liquid. An example of
it is when water vapor starts cooling in the atmosphere, it condensates into
tiny water droplets, which turn into clouds.
Okay, well that’s all I had to learn about this
week! Thanks for helping me! You guys are cool! :D Well, I hope I do well on my
test, and if you are taking it along with me, I wish you luck! Bye!
