Matter Test
Question | Answer |
---|---|
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 |
