Is There Chemistry<3

What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. There are four phases of matter they are solid, liquid, gas, and plasma. Solids have particles that can only vibrate because they are so close together. Solids have definite volume and shape and has the least amount of energy of all the four phases . Liquids particles are somewhat far apart. Liquids have no definite shape but has a definite volume. Gas particles are spaced far apart and they have no definite shape or volume. Plasma has the most amount of energy of all four. Its particles are spaced very far apart. Plasma is very unlikely on Earth but it is the most common phase in the universe. There are many changes in the states of matter. Here are a few...

Solid----------gas = sublimation ex: dry ice
Gas-----------solid = deposition
Liquid--------gas = vaporization
Gas----------liquid = condensation ex: clouds
Liquid-------solid = freezing ex: ice cubes
Solid--------liquid = melting ex: ice pop

An amorphous solid is a solid that can flow like a liquid under certain conditions.

There are two laws, Charles's Law and Boyle's Law. Boyle's law says that if the pressure increases the volume decreases and if the pressure decreases then the volume increases. Think of pumping a pump, the less pressure you put on it the more air fills up inside. Charles's Law says that if the temperature increases then the volume increases and if the temperature decreases then the pressure decreases.

Three interesting facts:
Dry Ice is solid Carbon Dioxide.
Two examples of an amorphous solid are candle wax and glass.
A viscous substance is in the liquid phase.

I loved this lesson on Chemistry because I got to do a lot of experiments and I learned facts that I never knew before. For example I never knew what an amorphous solid was or what the four phases of matter is but now I do.
