Physical Properties Flashcards
(16 cards)
A characteristic of matter that can be observed or measured without changing the identity of the matter is
Physical property
Some examples of physical properties are
- color
- odor
- magnetism
Ex: aluminum cube can be flattened into sheets of foil
Malleability
Ex: an ice cube floats in a glass of water
State
Ex: copper can be pulled into thin wires
Dulictility
Ex: plastic foam protects you from hot liquids
Thermal conductivity
Ex: flavored drink dissolves into water
Solubility
Ex: an onion gives a very distinctive smell
Odor
Ex: a golf ball has more mass than a table tennis ball
Density
Density is __________ that describes the relationship between mass and volume
Ration
Which layer would settle at the bottom of the graduated cylinder?
The most dense
What will the least dense liquid be found?
At the top of the graduated cylinder
If you know the density of a substance how can you determine if it will float in water?
You need to measure its mass and volume and see which one is more dense
The units of density take the form of a mass unit divided by what?
A volume unit
Freezing and melting are what kind of change?
Physical changes
What DOES NOT happen when a substance goes under physical change
It’s identity does not change
