Mass, Volume, and Density Flashcards
Anything that has mass and takes up space
Matter
Refer to the different properties of a substance that can change its state without changing the identity of the substance
Physical Properties
Amount of matter in an object
Mass
Measures the inertia of an object and is measured in grams (g)
Mass
Amount of space an object occupies and is measured in liters (L)
Volume
Mass of an object divided by its volume
Density
Measure of how much matter is packed into a given space and is measure in grams per liter (g/L)
Density
The density of a substance can be effected by its _____
Temperature
When a substance matter changes the ____ ____ also changes
Physical Property
Have a definite shape and volume
Solids
Least compressible state of matter as molecules are packed together in a tight pattern
Solids
Have a definite volume but take the shape of their container
Liquids
More compressible than solid as molecules are not packed tightly
Liquids
Have neither definite shape nor volume
Gas
Most compressible state of matter as molecules are far apart from each other
Gas
State of matter that is often found in stars
Plasma
Gas that is ionized
Plasma
Electrons have been stripped from the atoms
Ionized
Phase of a substance is dependent on 2 conditions
Temperature and Pressure
Measure of average kinetic energy of the molecules in substance
Temperature
The ____ the temp the more energy the molecules have (move faster) and the more space they take up
Higher
Measure of the force exerted on an object by the surrounding atmosphere
Pressure
The ____ the pressure the more molecules are forced together
Higher
The higher the pressure the more molecules are forced together this will cause water to change from ___ to _____
Gas to Liquid
Pressure decreased the molecules of water will be forced further apart causing change from ____ to ___
Liquid to Gas
Refer to the ability of a substance to change its identity, can happen when the substance undergoes a chemical reaction
Chemical Properties
Process of a gas changing into a liquid
Condensation
Happens when the molecules of the gas slow down and become closer together
Condensation
Process of a liquid changing into a gas
Evaporation
Happen when the molecules of the liquid gain enough energy to break away from the surface of the liquid
Evaporation
Process of solid changing into liquid gas
Sublimation
Happen when the molecules of the solid gain enough energy to break away form the surface of the solid
Sublimation
Process of gas changing to a solid
Deposition
Happens when the molecules of the gas slow down and become closer together
Deposition
Process of a solid changing to a liquid
Melting
Happen when the molecules of the solid gain enough energy to break away from each other
Melting
Process of a liquid changing to a solid
Freezing
Happens when the molecules of the liquid lose enough energy to stay together
Freezing
