use a reliable source to determine the atmospheric pressure at your location (atmospheric pressure at sea level is 101325 PA and atmospheric pressure in Denver Colorado is 84000 Pa). Use the equation percent difference between your experimental value (actual atmospheric pressure). show all work. what are some possible sources of errors in your experiment?
