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.

In the wise words of Dan Gable, an Olympic gold medalist, "Gold medals aren't really made of gold. They're made of sweat, determination, and a hard-to-find alloy called guts." At the melting point of gold 1064.18ºC, the heat of fusion, ΔHfus, is +12.55 kJ/mol and at the normal boiling point of 2836ºC, the heat of vaporization, ΔHvap, is +334.4 kJ/mol. How much heat must be applied to melt a 3.52 g sample of gold? Report your answer in kilojoules to 3 sig figs, but do not include units in the answer.
