Keeping track of units during conversions can get confusing. Therefore, a good strategy is to use dimensional analysis. In dimensional analysis, Part A conversion factors are used to cancel out unwanted units and leave the desired units. Consider the following example: How many football fields could fit on a 1 mile stretch of land? Here are The conversion factor relating miles to meters is 1 mile = 1610 m. the relevant conversion factors: The speed of light is 3.00 x 108 m/s. How fast is this in miles per hour (miles/h)? 1 football field = 100 yards • View Available Hint(s) 1 mile = 5280 ft 1 yard = 3 ft 1 ΑΣφ ? Then 1 pmile x 5280 K 1 yard 1 football field miles/h 1 pmite 3 100 yards = 17.6 football fields Part B The conversion factor relating feet to meters is 1 ft = 0.305 m. Keep in mind that when using conversion factors, you want to make sure that like units cancel leaving you with the units you need. You have been told that a certain house is 164 m2 in area. How much is this in square feet? • View Available Hint(s) 1 ΑΣφ ft?

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.
