States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

Why is it that people can wear diamonds under normal conditions without having to keep them under high pressure?
O A thin layer of oxidized carbon forms on the outenlayer of the diamond structure, preventing the conversion of diamond
to graphite.
Diamonds are thermodynamically unstable, but appear to be stable because the rate of conversion to graphite is
very slow.
Diamond is the stable form of carbon under normal conditions.
O A small amount of the diamond does convert to graphite; however, the equilibrium greatly favors the reformation
of diamond.
