gonzales (pag757) – H08: Gas Laws – McCord – (53130) 1 This print-out should have 22 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Divers know that the pressure exerted by the water increases about 100 kPa with every 10.2 m of depth. This means that at 10.2 m below the surface, the pressure is 201 kPa; at 20.4 m below the surface, the pressure is 301 kPa; and so forth. If the volume of a balloon is 2 . 8 L at STP and the temperature of the water remains the same, what is the volume 44 . 72 m below the water’s surface? Answer in units of L. 002 10.0 points A gas is enclosed in a 10.0 L tank at 1200 mm Hg pressure. Which of the following is a reasonable value for the pressure when the gas is pumped into a 5.00 L vessel? 1. 24 mm Hg 2. 2400 mm Hg 3. 0.042 mm Hg 4. 600 mm Hg 003 10.0 points At standard temperature, a gas has a volume of 237 mL. The temperature is then increased to 138 C, and the pressure is held constant. What is the new volume? Answer in units of mL. 004 10.0 points A sample of gas in a closed container at a temperature of 84 C and a pressure of 8 atm is heated to 370 C. What pressure does the gas exert at the higher temperature?
