Properties Of Matter Flashcards
(23 cards)
To be considered matter an object must have
Mass and volume
The amount of matter in an object is it’s
Mass
Weight is a combination of
Mass and gravity
The milli prefix means
1000
How close a series of measurements are to each other is called
Precision
Any property of matter that can be observed without changing the matter is called __________________ property.
Physical
The volume of an irregular solid is best observed using
Water displacement
A ________________ property can sometimes be used to identify a sample of matter’s identity without changing it
Physical
A solid becoming a liquid is called a ________________ change.
Phase/physical
Any change that results in the formation of a new type of matter is called a __________________ change.
Chemical
The combination of mass and ________________ is called density.
Volume
The base unit for time is the
Second
The base unit for length is the
Meter
How close a measurement is to the actual value being measured is called
Accuracy
A characteristic of a sample of matter that can only be observed by changing the identity of the matter is called a ______________ property.
Chemical
If you are measuring the length of an ant the most reasonable unit would be the
Millimeter
The length of this room would best be measured in
Meters
The Si base unit for temp is the
Kelvin
Mass per unit volume is called
Density

1000
What is the formula for f
Density
Mass/volume
Weight is
Mass x gravity
What is a physical change
Change in form but not identity
