A puddle of water slowly shrinks in the sun. After a few hours, the puddle has dried up completely. Is this an exception to the law of conservation of mass? Why or why not?
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.
The law of conservation of mass, also known as the principle of mass conservation, is a fundamental principle that states that the mass of a closed system of substances will remain constant, regardless of any physical or chemical changes that occur within that system.
