States of Matter
What state of matter has a definite shape and definite volume?
Solid
What is the change of state from a liquid to a gas that usually occurs at the surface of a liquid over a wide range of temperatures?
Evaporation
A substance that cannot be separated or broken down into simpler substances by chemical means.
Element
Is cooking a physical or chemical change?
chemical change
What is a homogeneous mixture of 2 or more metals?
Alloy
What state of matter has an indefinite shape and indefinite volume?
Gas
What is the change of state from a gas to a liquid?
Condensation
A substance made up of atoms of two or more different elements joined by chemical bonds.
Compound
Is freezing a physical or chemical change?
physical change
What is a heterogeneous mixture?
A mixture that is not uniform in composition; components are not evenly distributed throughout the mixture.
What state of matter has an indefinite shape and a definite volume?
Liquid
What are the 2 types of vaporization?
Evaporation and Boiling
Mass cannot be created or destroyed in a chemical reaction.
Law of Conservation of Mass
How do you know that baking soda fizzes with vinegar when they are combined is a chemical change?
They fizz/create bubbles
What is a homogeneous mixture?
A mixture that is uniform in composition; components are evenly distributed and not easily distinguished; also known as a solution.
Solids have very _____ intermolecular forces
Strong
What's the process in which a solid changes directly into gas?
Sublimation
Scattering of a light beam as it passes through a mixture; a test to determine if mixture is heterogeneous (a colloid or a suspension)
Tyndall Effect
List 3 ways to know if a physical change has occurred;
boiling, melting freezing - only affects the physical properties of matter
What is a mixture that is uniform in composition; components are evenly distributed and not easily distinguished; also known as a homogeneous mixture?
A solution
What is the most common state of matter in the universe?
Plasma
What is the process in which a gas changes directly to a solid without going through the liquid state?
Deposition
This theory states that all matter is made up of tiny particles, those particles are always moving, and as the particles get hotter, they move faster.
Kinetic Theory of Matter
List 3 ways to know if a chemical change has occurred
New gas is formed (bubbles or odor), energy is released, energy is absorbed, a precipitate forms, and sudden change in color
Which is the solvent and which is the solute?
The solvent is the substance that is capable of dissolving other substances and the solute is the substance that is dissolved in the solution.
