Avogadro's Hypothesis T & ___, volumes of gas P equal _____ • At the same ___ equal number moles (n) (effectively must contain equal _____. of particles/molecules) All at: P = 1 atm T = 25 o. C V = 1. 0 L CO 2 He O 2 Avogadro's Law (V & n) n↑, V↑ directly proportional 1 mol add gas He 2 mol He

inversely proportional P↑, V↓ directly proportional T↑, V↑ T↑, P↑ n↑, V↑

seen before but good to remember average KE (which already considers mass) is directly proportional to temperature ↑Temp as ↑KEavg 373 K 273 K o K = C + 273. 15 0 K – 273 o. C. 15 – 459. 67 o. F no KE absolute zero
