Physical properties lesson 2 8th grade outline
physical property
A characteristic of matter that you can observe or measure without changing the identity of matter
Unique
Every element and compound have a ______ set of properties
Changes and not
Weight _______ with location but mass does _______
Whether its value depends on the size of a sample
What determines if a property is size-dependent?
The arrangement of atoms
What determines the physical properties of matter?
Mass and volume
What two properties must you 👆 must know to determine density
Magnents
_______ can be used to separate materials that contain iron from other materials
State
_______ of matter is a physical property
Melting and boiling
_________ point and ________ point are size-independent properties
Mass
A size-dependent property because it it is a measure of the amount of matter in a sample
Filtering
A solid can be separated from a liquid by ______________ if the solid does not dissolve in the liquid
True
Atoms that make up a compound are bonded together; they cannot be separated by physical means. True or False?
Weight
Mass is sometimes confused with ________; the pull of gravity on matter
False
Mass is the weight of an object. true or false?
Densities
Oil and water can be separated because they have different _________
Size-dependent
Some physical properties are ________-___________, which means the measurement of the property depends on how much matter is present
Lower
Salt and water can be separated because the boiling point of water is much ______ than salt's
Yes
Solubility and melting point are two examples of physical properties. Yes or no?
size independent
Some Physical properties that are ________-____________ because they do not depend on how much matter is present
Electrical conductivity
The ability of matter to carry electric current
thermal conductivity
The ability of matter to carry thermal energy
Solubility
The ability of one substance to dissolve into another
Density
The amount of mass per unit volume
Volume
The amount of space something takes up
Solid, liquid, and gas
The common states of matter on Earth
Dividing
The density of an object can be calculated by ___________ its mass by its volume
Seperated
The parts of a mixture can be _________ using the physical properties of the components
Close and fast
The state of matter depends on how _____the particles are in an object and how ______ they move
Boiling point
The temperature at which a liquid changes to a gas
melting point
The temperature at which a solid changes to a liquid
