Which question can the latent heat of solidification most directly answer? A.How much heat is released into the environment when 1 kg of the substance freezes? B.At what temperature will the substance change from a liquid into a solid? c.How much energy must be removed to lower the temperature of the liquid substance while it freezes? d.How much pressure does it take to lower the freezing point of the substance by 1 °C?
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.
