Matter
answer
Anything that has mass and takes up space
question
Mass
answer
The amount of matter in an object
question
Properties
answer
Appearances of an object including: mass, magnetism, physical state, relative density, solubility, and the ability to insulate or conduct heat or electricity
question
Magnetism
answer
The property of attraction to a magnet
question
Physical State
answer
The classification of matter as a solid, a liquid, or a gas
question
Relative Density
answer
Objects that are more dense sink in water; less dense objects float in water
question
Solubility
answer
Measurement of the ability of a solid to dissolve in a liquid
question
Thermal Energy
answer
Energy that causes a change in temperature between materials
question
Electrical Energy
answer
Energy produced by the movement of electrons
question
Conductor
answer
Material that allows electric current or heat energy to flow through easily
question
Insulator
answer
Material that slows down or stops electric current or heat from flowing
question
Classify
answer
Group together based on similar traits
question
Constant
answer
Not changing; the same
question
Boiling Point
answer
The temperature at which a substance changes states from a liquid to a gas (the boiling point of water is 100 degrees Celsius or 212 degrees F)
question
Melting Point
answer
The temperature at which a substance changes states from a solid to a liquid
question
Freezing Point
answer
The temperature at which a substance changes states from a liquid to a solid (freezing point of water is 0 degrees Celsius or 32 degrees F)
question
Condensation
answer
Physical change in matter from a gas to a liquid
question
Evaporation
answer
Physical change in matter from a liquid to a gas.

tighter-knit particles in no particular pattern
question
The solid state of matter consists of
answer
very close-knit particles in a definite pattern
question
Water has a definite
answer
shape and volume in the solid state
question
Matter can be classified based on its physical properties using tools such as
answer
triple beam balances, magnets, or electrical circuits
question
Matter can be classified based on its behavior such as
answer
if it will sink or float in water, attract to magnets, if it is soluble in water, or conduct heat or electricity.
question
