Question
Human-made sulfates can form these substances when expelled into the air, causing smog and regional atmospheric cooling. For 10 points each:
[10e] Give this term for solids or liquids dispersed in a gas. These colloids are contained in spray cans.
ANSWER: aerosols [accept, but DO NOT REVEAL, atmospheric particulate matter; prompt on sols]
[10m] The solids and liquids in an atmospheric aerosol are given this name. Air quality indices often report numbers for this term alongside subscripts of 2.5 or 10, depending on the diameter of the dispersed non-gases.
ANSWER: particulate matter [or atmospheric particulate matter or particulates; accept PM; accept PM2.5 or PM10]
[10h] Smog and acid rain are also caused by these non-sulfur-containing gases, which form in the atmosphere via the Zeldovich mechanism. You can either name the two specific gases or the abbreviated term that refers to both.
ANSWER: nitrogen oxides [or NOx (“nocks”) gases; or NO AND NO2; accept nitric oxide in place of “NO”; accept nitrogen dioxide in place of “NO2”; prompt on partial answers]
