1
is anything that occupies space and has mass
matter
2
is the amount of matter in an object the more matter is present in an object means the greater its___ it is usually expressed in grams or kilograms
mass
3
materials that are compact have relatively greater___ than those with a hollow interior, is also independent on gravity
mass
4
it is the measure of force that acts on an object it is expressed as the amount of matter multiplied by the gravitational force that acts on it the greater the gravitational force that acts on an object the heavier it weighs it is expressed in newtons is dependent on gravity
weight
5
it is the amount of space occupied by matter it can be measured using instruments with graduations or by getting the dimensions of the object it is expressed in liters for liquids or cubic length for solids
volume
6
it is expressed in kilograms per cubic meter or grams per cubic centimeter it is the ratio between mass and volume it tells how compact an object is an object with the greater mass has more compact particles than the lighter ones
density
7
it is the ratio of a substance density to a standard substance it is also known as relative density it is a dimensionless quantity
specific gravity
8
these are qualities that are readily observable or measurable without changing the matters composition general properties such as mass volume weight density and specific gravity are all examples of physical properties these are often used to describe or observe matter
physical properties
9
it is the temperature at which a solid matter changes to liquid
melting point
10
it is the temperature at which turns into a solid matter
freezing point
11
it is the temperature at which liquids evaporates the vapor pressure is equal to the pressure of its surrounding liquid at this temperature
boiling point
12
it is the ability of a solute to dissolve in a given solvent it is varies depending on its composition it is considered as a physical property as one can tell whether a material is soluble or not by merely observing its physical appearance
solubility
13
these are qualities that are observed specifically in metals
metallic properties
14
it is the ability of a material to allow heat or electric charges to pass through easily materials can be thermal or electrical conductors
conductivity
15
it is the ability of a material to be flattened into thin sheets
malleability
16
it is the ability of a material to be easily drawn into wires
ductility
17
