Most of the volume occupied by gas
is empty space
Gases are in
constant random motion
Collisions between gas particles with 1 another/container are
elastic collisions
Gas particles have
no forces of attraction inbetween
Gas’s kinetic energy is
dependent on the gas temperature
Temperature increase =
Increase of kinetic energy
Weakest
LDF
Medium
D-D
Strongest
H-Bond
Q
heat energy absorb/released, (J)oules
m
substance mass, Kg
c
specific heat, J/g*c
ΔT
Change in temp, Celsius/Kelvin
formula
Q=mcΔT
