Screen Reader Description: The Ordinary Phases of Water. Image: Graph of Temp (Kelvins from 0 to 700) on X axis, P (atm) on Y axis (from 10 to the power of 0 to 10 to the power of 8, pressure, (P a)). There is a curve starting at 200 on the X axis and 10 to the power of 0 on the Y axis. The line goes upward to the right to finish at 610 on the X axis and 10 to the power of 7 on the Y axis. There is a straight line with a slightly negative slope starting at 260 on the X axis and 10 to the power of 8 on the Y axis that goes downward until it hits the curve and stops. To the left of the straight line is the word "Solid". Between the straight line on the right and the curve is the word "Liquid". To the right side of the curve is the word "Gas". End of image. The critical temperature is: 0 K 100 K 200 K 300 K 400 K 500 K 600 K 700 K 100 Pa 101 Pa 102 Pa 103 Pa 104 Pa 105 Pa 106 Pa 107 Pa
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.
