mass and volume
Makes up everything around us
Matter
explains the properties of substances with three fundamental postulates
kinetic theory of matter
the resistance to movement of fluids and gases
viscosity
cannot be broken down into simple substances by physical methods. can be simple or compound
pure substances
the sollute particles are not dissolved and instead are floating in the entire volume and will settle after some time
suspensions
measure of the amount of matter in a body
mass
Under conditions of of temperature and pressure at the earth's surface, matter occurs in three states of matter
solid, liquid, and gas
if it can decrease in volume under the action of a force
compressible
Contain several pure substances which can be separated by physical methods. It can be heterogenous or homogenous.
mixtures
mixtures with properties between those of suspensions and solutions. example used in cooking are emulsions
colloids
the space occupied by an object of mass
volume
has definite volume
liquids and solids
pressure exerted by the atmosphere on us
atmospheric pressure
can differentiate the component substances with the naked eye because the properties are different in different parts.
heterogenous mixture
C=Ms/Vt
concentration
its IS unit is the kg
mass
states that matter occupys entire space available to them
gas
d=m/v
substance by which we have more quantity
solvent
the concentration of the saturated solution at the given temperature
solubility
Its IS unit is m3
volume
tends to flow
liquids and gases
has lower mass than water even though it is a solid
ice
salt in water is an example of a
homogenous mixture
Ms(solute)/Mt(solution) x100
percentage of mass
