4 How are the processes of vaporization and condensation similar? A solid turning to a liquid is an example of You are outside on a very hot day and see mud puddles in your yard. Later that day, you notice the mud puddles have dried up. This is an example of Melting O Evaporation O Boling O Condensation V OK N l'll come back When a liquid changes to a gas At room temperature, nitrogen does not have a shape or volume. Which state is it in? There are three main states of matter: solid, liquid, and gas. All have different physical properties. Which statement describes the physical state of a gas but not of as or liquid?
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.
