Unformatted text preview: guo (rg27533) – Homework 7 – Sutcliffe – (52380) 1 This printout should have 20 questions. Multiplechoice questions may continue on the next column or page – find all choices before answering. 001 10.0 points A gas has a pressure of 6 . 21872 atm when its volume is 2 . 78 L. What will the pressure be when the volume is changed to 1 . 67298 L, assuming constant temperature? Express the final pressure in torr. Answer in units of torr. 002 10.0 points For an ideal gas, pressure has what relation ship to volume provided only pressure and volume are allowed to change? 1. inversely proportional 2. proportional 3. unrelated 4. equal 003 10.0 points Which of the following is a true statement about a fixed amount of ideal gas at constant pressure? 1. If a sample of gas is heated from 0 ◦ C to 273 ◦ C, the volume will double. 2. If a sample of gas is heated from 100 ◦ C to 200 ◦ C, the volume will decrease by a factor of two. 3. If a sample of gas is cooled from 400 ◦ C to 200 ◦ C, the volume will decrease by a factor of two. 004 10.0 points A sample of a gas occupies 2110 mL at 36 ◦ C and 740 torr. What volume would it occupy at the same pressure and 419 ◦ C? Answer in units of mL. 005 10.0 points A 678 mL gas sample at STP is compressed to a volume of 263 mL, and the temperature is increased to 38 ◦ C. What is the new pressure of the gas in Pa?...
