Using the heating curve of WATER to answer the following questions, if point 5 represents 100 liquid water 1. Identify the region of the graph where the particles are moving with the smallest average spe 2. Identify the physical state of point 6 Liquid + Gas 3. What is occurring in region 2-> 3 in terms of physical change Melting 4. In which region does the substance have a definite shape and definite volume 5. What's the name of the process 5> 6 in terms of physical change Vaporization 6. How is energy changing during 3 -> 5 7. How is energy changing from 7-> 6 Condensation
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.
