Matter

Matter Test

QuestionAnswer
Matter is anything that has mass and volume
Solids definite shape and volume
Liquids definite volume, but No definite shape
Gases No define volume or shape
Plasma Gas like mixture of + and ---- charged particles
Viscosity Measure of the material resistance to flow
Elasticity Measure of ability to be stretched and then return to its original size
Brittleness measure a material's tendency to shatter upon impact
Hardness Resistance to breaking or scratching
Tensile Strength Measure of how much pulling, or tension, a material can withstand before breaking
Malleability Ability to be hammered into sheets
Luster shininess
Ductility ability to be pulled into wires
Density The amount of mass in a given volume How tightly packed the atoms or molecules are in a substance g/ML or G/L for liquids g/cm for solids
Fluids Any matter that is able to flow Liquids and gases Density of a liquids might be different from the density of the same solid Most materials are denser in solid phrase than their liquid phrase
Exception Water freezes with air spaces so it is less dense and floats Density of water is 1g/cm
Buoyancy Upward force a fluid exerts on an object Determines whether the subject will sink or float
Boiling Point Temperature at which a liquid changes into a gas
Melting Point Temperature at which a solid changes to a liquid changes to a solid
Evaporation process at which a liquid changes to a gas at boiling point
Condensation Process at which a gas becomes a liquid Gas cooled below its boiling point
Sublimation When a solid changes directly to a gas The matter doesn't melt
Deposition Gas changes directly into a solid
Atoms are held close together by strong bonds and movement is slow is called Solids
Crystalline Solids Atoms are arranged in regular fashion
Amorphous Solids atoms LACK a regular arrangement
Bonds are weaker and atoms are spaced father apart They take the shape of container they are in Liquids
Bonds are weakest and atoms far apart Expand to fill the container they are in Gases
Movement very rapid 99% of mass of our solar system Plasma
High-viscosity liquids take longer to flow Low viscosity liquids flow easier Temperature raising- viscosity decreases except in gases Viscosity
Rubber band, Elastic, and Playground Balls are examples of Elasticity
Gold and Silver Coins, Aluminum Foil and Soda cans are example of Malleability
Sulfur, Calcium and Glass is an example of Brittleness
Diamonds are an example of Hardness
Gold Silver, Mercury are examples of Luster
Most Metals (copper, silver) is an example of Ductility
Property of fibers, ropes, cables, girders DuPont Kevlar-5 times tensile strength of steel are examples of Tensile Strength
Freezing Point Temperature at which a liquid changes to a solid.
Water vapor - water, dew in the morning, glass of ice tea in hot weather is an example of Condensation
Snow dry ice and glaciers is an example of Sublimation
Sun, Stars and Lightning is an example of Plasma
Why is water unusual because it expand when it goes from liquid
What happens to the viscosity of water as you increase the temperature decrease except in gases
Water is unusual because it _________ when it goes from liquid to a solid state Expand
As a sample of matter is heated, its particles Moves
The particles that make up a solid move ____________________ than do the particles that make up a gas. Slower
A fluid's resistance to flows called vicosity
Matter in which atoms are tightly held in place is a Density
Matter in which particles are free to move in all directions until they have spread evenly throughout their container is a Liquid
