Unformatted text preview: Chemistry‌ ‌ 11.1‌ ‌ a. The‌‌average‌‌kinetic‌‌energy‌‌of‌‌gas‌‌molecules‌‌is‌‌proportional‌‌to‌‌kelvin‌‌temperature‌‌-‌‌the‌‌ higher‌‌the‌‌temp,‌‌the‌‌faster‌‌the‌‌movement‌ ‌ b. The‌‌actual‌‌volime‌‌occupied‌‌by‌‌gas‌‌molecules‌‌is‌‌extremely‌‌small‌‌compared‌‌to‌‌the‌‌ volume‌‌that‌‌gas‌‌occupies,‌‌making‌‌it‌‌easy‌‌to‌‌compress‌‌into‌‌very‌‌small‌‌particles‌ ‌ c. The‌‌attractive‌‌forces‌‌between‌‌particles‌‌of‌‌gas‌‌are‌‌usually‌‌very‌‌small,‌‌making‌‌them‌‌less‌‌ dense‌ ‌ 11.2‌ ‌ a. The‌‌gas‌‌particles‌‌move‌‌randomly‌‌at‌‌high‌‌velocities,‌‌so‌‌when‌‌they’re‌‌exposed‌‌to‌‌oxygen‌‌ and‌‌it‌‌combusts,‌‌the‌‌particles‌‌move‌‌quickly‌‌out‌‌which‌‌causes‌‌the‌‌explosion‌‌reaction‌‌to‌‌ occur.‌‌Also‌‌see‌‌law‌‌number‌‌4 ‌ ‌ b. Higher‌‌temperature‌‌=‌‌higher‌‌pressure‌ ‌ c. Again,‌‌see‌‌number‌‌4.‌‌The‌‌particles‌‌move‌‌quickly‌‌which‌‌carries‌‌the‌‌scent.‌ ‌ 11.4‌ ‌ a. Heat‌‌of‌‌gas‌‌(in‌‌kelvin‌ ‌ b. Amount‌‌of‌‌gas‌ ‌ c. Liters‌‌(volume‌‌of‌‌gas)‌ ‌ d. Moles‌‌of‌‌gas‌‌(specifically‌‌Helium)‌ ‌ 11.6‌ ‌ a. ‌yes‌ ‌ b. ‌no‌ ‌ c. ‌no‌ ‌ d. yes‌ ‌ 11.8‌ ‌ a. 467/2‌ ‌ b. 467torr‌ ‌ c. Same‌‌amt‌‌in‌‌HG‌ ‌ d. 934‌‌Pa‌ ‌ 11.10‌ ‌ a. The‌‌pressure‌‌and‌‌the‌‌heat‌‌causes‌‌the‌‌particles‌‌to‌‌expand,‌‌therefore‌‌expanding‌‌the‌‌ distance‌‌between‌‌particles‌‌and‌‌the‌‌bag.‌ ‌ 11.14‌ ‌ a. Diagram‌‌c ‌ ‌ b. Diagram‌‌b ‌ ‌ c. Diagram‌‌a ‌ ‌ ‌ 11.16‌ ‌ a. Volume‌‌changes‌‌to‌‌current‌‌volume(3)‌ ‌ b. Current‌‌volume/2‌ ‌ c. Current‌‌volume‌‌/.8‌ ‌ ‌ 11.18‌ ‌ a. New‌‌pressure‌‌is‌‌1.20/5‌ ‌ b. 25‌‌ml‌‌/‌‌1.2‌ ‌ c. 750/5*‌‌1.2‌ ‌ d. 8*5‌ ‌ ‌ 11.20‌ ‌ a. yes‌ ‌ ‌ 11.22‌ ‌ d. Pressure‌‌provides‌‌50*1500‌‌ml‌ ‌ e. .5atm‌‌provides‌‌7.60‌‌mmHg‌ ‌ f. 2.0‌‌atm‌‌provides‌‌a‌‌volume‌‌of‌‌25‌‌mL‌ ‌ g. Provides‌‌825g‌ ‌ ‌ 11.24‌ ‌ a. Same‌ ‌ b. Smaller‌ ‌ c.

Pressure‌‌increases‌‌by‌‌.5‌ ‌ 11.32‌ ‌ a. 10‌‌L‌‌heated‌‌to‌‌250‌‌torr‌ ‌ b. 680‌‌mmHg‌ ‌ 11.34‌ ‌ Pair‌‌a‌‌would‌‌not‌‌ ‌ Pair‌‌b‌‌would‌ ‌ Pair‌‌c‌‌would‌ ‌ Pair‌‌d‌‌would‌‌not‌ Pair‌‌e‌‌would‌ ‌ 11.36‌ ‌ a. The‌‌pressure‌‌is‌‌lower‌‌at‌‌sea‌‌level,‌‌meaning‌‌the‌‌particles‌‌move‌‌faster‌‌and‌‌are‌‌hotter‌ ‌ b. The‌‌heating‌‌ov‌‌the‌‌water‌‌to‌‌sterilize‌‌surgical‌‌equipment‌‌ensures‌‌that‌‌no‌‌living‌‌organisms‌‌ remain‌‌on‌‌the‌‌equipment.‌ ‌ ...
