"A 30.0-g sample of liquid gold at 1085°C is poured into a mold and allowed to cool to 18°C. calculate the amount of energy transferred during the process. (Hint: Note the freezing temperature of gold.)" I dont understand how your supposed to know the temperature at which gold freezes when its not given. Can it be calculated?

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.
