Document Summary
Matter: anything that takes up space and has mass. Separation of matter: distillation: to separate a homogeneous mixture of liquids, it is boiled to a easily vaporizable liquid that is then recondensed and collected, filtration: a mixture is poured through a funnel using filter paper. Properties of matter: physical: changing matter without changing its composition. Ex: boiling water: chemical: changing the composition of matter. Ex: rusting, burning, dyes fading or changing color. Seconds (s: definition: the amount of matter in an object, normally expressed in grams (1kg = 1000g) Temperature: fahrenheit (f) is used in the us, celsius (c) is used everywhere else, c = (f 32) / 1. 8, k = c + 273. 15. Volume: the amount of space an object takes up, commonly expressed in cubic centimeters (cm3) Intensive and extensive properties: extensive: dependent on the quantity of mater. Density: density = mass / volume, density order.
