kinetic theory of matter
all matter is made of atoms and molecules that act as tiny particles
kinetic energy
energy an object has due to it’s motion
an object has greater thermal energy if:
there are more particles
gases
exert pressure on the walls of an enclosed space, no definite shape/volume
what type of motion are gas particles
random motion
liquids
no definite shape, definite volume
volume of a liquid:
constant, because all forces of attraction keep particles close together
solids
definite shape AND volume, slowest moving particles
plasma
properties are similar to gases except they conduct electricity, no definite shape or volume
pressure
the result of a force distributed over an area
what affects pressure?
speed, mass, number of collisions between particles of gas and walls
when temperature rises, the kinetic energy of patricles…
increase
raising temperature of gas will increase:
pressure
the more particles -
the more collisions
charles law:
the volume of a gas is directly proportional to it’s temperature in Kelvins, -273.15*C
