A block of wood weighs 64.02 g and has the following dimensions: length of 15.0 cm, width of 11.0 cm, and thickness of 5.50 cm. 1. What is the volume of the block of wood in cubic centimeters (cc)? 2. From the given data, what is the density of the wood? (Density = mass / volume) 3. What is the area of a rectangular surface that is 0.640 inch wide and 1.140 inches long?
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.
