Tyndall Effect
Determines whether a substance is a mixture or a solution - use of particles and light pathways
Solution
Two or more substances mixed together - combining so the mixture appears to be only one substance
Mixture
A combination of two or more substances
Atmosphere
Solution of air surrounding the Earth
Water Cycle
Continuous movement of water from the atmosphere to the Earth and back again - through Evaporation, Condensation and Precipitation
Evaporation
Process where liquid gradually changes into a gas or vapor
Condensation
Transition of a gas into a liquid
Precipitation
When water droplets fall to earth - they become too heavy for the air to support them
Transpiration
Process where plants give off fresh water vapor
Groundwater
Water stored in spaces between rocks and sediment of the Earth
Boiling
Process where liquid rapidly changes into a gas at its boiling point
Desalination
Removing salts from a substance - usually ocean water, to make it drinkable
Distillation
Two step process where a solution is heated until it evaporates, leaving behind dissolved materials - then cooling the vapor back into liquid form and collecting it - Purifies the Earth’s water supply
Ocean
Largest liquid solution on Earth
Salt Water
Solution where the solvent is water and the solute is sodium chloride (table salt)
Density
Amount of particles (mass)in a certain space(volume)
Freshwater
Water that is purified through distillation
Ocean
Water is the biggest solvent in the ocean; there are many different solutes in the ocean - mostly sodium chloride (table salt); there are also solutes in the ocean that are gases-oxygen and carbon dioxide
