Composition of matter
A Homogeneous Mixture
What is mixture in which two or more substances are uniformly spread out?
A Solution
What is homogeneous mixture of particles so small that they cannot even be seen with a microscope and will never settle to the bottom of their container?
An example of physical property
What is color, size, shape, density, melting point, boiling point, etc?
Solid
What is matter with a definite shape and volume?
Physical change
What is change in size, shape or state of matter and substance doesn't change identity when it undergoes physical change?
A Heterogeneous mixture
What is mixture in which different materials can be easily distinguished?
A Colloid
What is type of mixture with particles that are larger than those in solution, but still too light to settle out?
An example of a chemical property
What is flammable, combustible, may react to light, etc?
Liquid
What is matter with an indefinite shape and definite volume?
Plasma
What is high temperature gas?
An Element
What is substance made up of atoms with same identity?
A Suspension
What is heterogeneous mixture containing a liquid in which visible particles settle?
Physical property
What is characteristic of a material that you can observe without changing the substance?
Gas
What is matter with an indefinite shape and indefinite volume
Effect which is used for: Detecting colloids by shining a beam of light at colloid making the light scatter
What is the Tyndall effect?
A Substance
What is type of matter with a fixed composition that cannot be separated by physical means?
An example of a colloid
What is Milk, Fog, Cool whip, etc?
Chemical Property
What is Characteristic of a substance that indicates whether it can undergo a certain chemical change?
Change from solid to liquid
What is Melting?
Buoyancy
What is the ability of a fluid (liquid or gas) to exert an upward force on an object immersed in it
The 2 types of Mixtures
What is Heterogeneous and Homogeneous?
A common hint to tell if a mixture is a Suspension?
What is if it needs shaking to mix, then it’s a suspension?
Chemical change
What is a change in one substance to another substance that cannot be reversed?
Gas to a solid without entering liquid state
What is deposition?
The Law of Conservation of Mass
What is the law that states that the mass of all substances present before a chemical change equals mass of all substances after the change?
