QUESTION 3 The enthalpy of vaporization is typically much greater than the enthalpy of fusion (melting, not atomic fusion). Why is this? Vaporization involves breaking all intermolecular forces and bonds, while fusion involves only breaking the intermolecular forces. The process of fusion (melting) disrupts only hydrogen-bond intermolecular forces, while vaporization affects all internuclear forces. Vaporization involves the weakening of all intermolecular forces, while melting requires the breaking of those forces. Vaporization involves the breaking of all intermolecular forces, while melting only requires the weakening of those forces. Fusion involves only the vibrational modes of a solid. 00000 QUESTION 4 Arrange the following in order of increasing solubility in water: C₂H5OH; CO₂: N₂O.
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.
