Many mistakes can be corrected early if students take the time to think well-nigh what size answer would be conceivable. For example, in question 2 if the pressure is decreasing, the plenty essential be increasing. A reasonable answer essential be greater than 9.65 L. 1. 2. What pull up stakes be the spate of a balloon at 98 kPa if its deal is 9.65 L at 235 kPa? P1 V1 P2 (Boyles) P1V1 = P2V2 V2 = P1V1 / P2 V2 = (9.65L) (235 kPa)/ (98 kPa) V2 = 23 L V1 P1 4. An exhaled air blab out underwater at 290. kPa has hatful 18.9 mL. What will be its volume at the waters surface where the pressure is 104 kPa. (Why must a diver exhale during ascent?) P 2 3. What pres sure is required to reduce the volume of gases in a cars cylinder from 48 cm3 at V1 102 kPa to 5.2 cm3?

V2 P1 (Boyles) P1V1 = P2V2 P2 = P1V1/V2 P2 = (102 kPa)(48cm3)/(5.2cm3) P2 = 940 kPa (Boyles) P1V1 = P2V2 V2 = P1V1 / P2 V2 = (290.kPa)(18.9mL)/(104kPa) V2 = 52.7mL divers(prenominal) must exhale or else the gas in their lungs will expand so much that his lungs could rupture. 5. , V1 P1 6. A gas essay has volume 3.00 dm3 at 101 kPa. What will be the volume if the pressure is reduced to 14.2 kPa? P2 (Boyles) P1V1 = P2V2 V2 = P1V1/ P2 V2 = (9.24 dm3)(101 kPa)/(14.2 kPa) V2 = 65.7 dm3 If you want to get a near essay, order it on our website: BestEssayCheap.com
