is anything that occupies space and has mass

matter

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

materials that are compact have relatively greater___ than those with a hollow interior, is also independent on gravity

mass

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

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

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

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

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

it is the temperature at which a solid matter changes to liquid

melting point

it is the temperature at which turns into a solid matter

freezing point

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

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

these are qualities that are observed specifically in metals

metallic properties

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

it is the ability of a material to be flattened into thin sheets

malleability

it is the ability of a material to be easily drawn into wires

ductility

general properties of matter

mass weight volume density specific gravity

physical properties

melting point freezing point boiling point solubility

metallic properties

conductivity malleability ductility

measurement of gravity
