internal energy
the sum of all the kinetic energies and potential energies of all particles. the kinetic and potential energies are randomly distributed
ways to increase internal energy
do work on the system, increase the temperature
specific heat capacity
the energy required to increase the temperature of 1kg of a substance by 1 degree celcius without changing state
specific latent heat
energy required to change the state of 1kg of a material without changing its temperature
boyle’s law
when temperature is constant, pressure and volume are inversely proportional
charles’ law
when pressure is constant, volume is directly proportional to absolute temperature
pressure law
when volume is constant, pressure is directly proportional to temperature
molar mass
the mass of one mole of a substance
work done on gas to change volume equation
pressure x change in volume
brownian motion
the random motion of larger particles in a fluid caused by collisions with surrounding particles
ideal gas assumptions
random motion, no force of attraction between particles, particles have negligible volume compared to volume of container, elastic collisions, durations of collisions is short compared to time between collisions
