The normal melting point of aluminum is 655 0C and the normal boiling point is 2425 0C. The molar heat capacities of aluminum solid, aluminum liquid and aluminum gas are 24.35, 24.21, and 21.38 J/mol-K, respectively. The enthalpy of vaporization of aluminum is 11.370 kJ/g, and its enthalpy of fusion is 376 J/g. How much heat is released when 36.82 gram of 3732.78 0C aluminum gas changes to 78.1 0C solid? __________ kJ
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.
