Compound y has a heat of fusion of 361 J/g. The solid form has a specific heat capacity of 0.353 J/gºC and the liquid form has a specific heat capacity of 2.31 J/gºC. The freezing point of compound y is -15.6ºC. How much energy will it take to convert a 330.4 g solid sample of y at -33.3ºC to a sample at 43.6ºC? Give your answer in kJ, make sure it is rounded to the correct number of sig figs.
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.
