Lesson 2 – From Particles to Solutions Learning Goal: By the end of the class, I will be able to: THE PARTICLE THEORY 1. All matter is made up of tiny __________________ 2. Different substances are made up of _______________ kinds of particles. 3. The particles are always _______________. 4. The particles of a substance move_______________as its temperature _______________. 5. Particles _______________ each other. • These forces are _______________ when the particles are _______________ together. PROPERTIES OF MATTER _______________ is anything that has _______________ and _______________. _______________ is a measure of the _______________ of matter in an object. • Measurements – kilograms _______________or grams _______________ • Ex. A brick has more mass than an equal-sized volume of Styrofoam 1 _______________ is a measure of how _______________ an object is or how much space a _______________ takes up. • Measurements for a __________ – Litres ___________or millilitres ___________ • Measurements for a __________ – ___________ or ____________ • length (l) x width (w) x height (h) 3 ___________x 2 __________ x 1 __________ = 6 __________ • Ex. A volleyball is larger than a baseball. PURE SUBSTANCES A _______________ substance is made up of only _______________ type of particle. • Ex. Distilled H2O (tap H2O is not pure because it contains dissolved gases) It is either an _______________or _______________. • Ex. Carbon (C) is an element & sugar is a compound (C6H12O6) An _______________ is a _____________ substance that _____________be broken down. • Ex. Oxygen (O or O2) A _______________ is made up of _______________ or _______________ elements that are combined together chemically. _______________broken down. • Ex. Water (H2O) MIXTURES A _______________ contains _______________ or more _______________ substances. 1. A _______________ mixture _______________is when _______________ or more _______________ substances are mixed together. It is made up of more than _______________ particle and you can see _______________ than one part. • Ex. Chocolate chip cookie 2. A _______________ mixture _______________is made up of more than _______________ particle but you can only see _______________ phase. One particle is _______________ in another. • The different substances that make it up are _______________ individually visible. • Separate particles are not visible because one dissolves in the other = ___________ o Ex. Sugar dissolved in tea 2 SOLUTE VS SOLVENT Example 1: Sugar dissolved in tea • Sugar is the _______________ gets dissolved. • Tea is the _______________, dissolves the other substance. Example 2: Salt dissolved in water • Salt is the _______________ gets dissolved. • Water is the _______________ dissolves the other substance. The _______________ is the _______________ quantity while the _______________ is the _______________ quantity.
