Chem 1010 9/6 – 9/8/2017 Class Notes Area The area of a plane rectangle = length x width Area of plane triangle = height x base / 2 Area enclosed by a plane circle = pi x radius 2(squared) Three Dimensional objects have a surface area Volume, V In three dimensions we are more interests in volume. Volume is a measure of how much stuff you’ve got, a quantity of matter Liter is commonly used for fluids Liter was originally a base unit in the metric system Density Density is defined as mass / volume; d = m / V Water: 1.00 g per mL (1.00g/mL) –NEED TO KNOW- Temperature The volume increases as the temperature increases Celsius 100 C degrees=180 F degrees, 5 C=9 F degrees To Convert to F to C: calculate how many F degrees away from 32F Add or subtract 32
