  1. ANSWERS to HMK Questions 1-7 for Lesson 0.5 (Page 28)

  2. 1. Examine the following set of data: Which of the equations below best describes the relationship shown? X1Y1 = X2Y2 DIRECT

  3. 2. Examine the following set of data: Which of the equations below best describes the relationship shown? X1Y1 = X2Y2 INVERSE

  4. 3. If you have 5.6 L of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be? P1 x V1 = P2 x V2 1.5x 5.6= P2 x 4.8 4.8 4.8 P2 = 1.8 atm

  5. 4. The temperature of air in a balloon at sea level (1.0 atm) is 25°C. If you take the balloon with you to Denver, where the air pressure is 0.85 atm, what will the new temperature inside the balloon be if the volume remains constant? P1 P2 T1 = 25 + 273 = 298 = T1 T2 1 0.85 T2 = 298 x 0.85 = 253 K = 1 298 T2

  6. 5. A 2.0 L container of nitrogen has a pressure of 3.2 atm and a temperature of 32°C. What would the new temperature of the nitrogen be if you decreased the pressure to 1.0 atm and enlarged the container to 3.0 L? P1V1 P2V2 = T1 = 32 + 273 = 305 K T1 T2 (3.2)(2.0) (1.0)(3.0) = T2 = (305x1x3)= 143 K 305 T2 (3.2x2.0)

  7. 6. Deadly chlorine gas occupies a volume of 25 mL at 300 K. What volume will it occupy at 600 K? V1 V2 = T1 T2 25 V2 T2 = 25 x 600 = 50 mL = 300 300 600

  8. 7. A bag of potato chips is packaged at sea level (1.00 atm) and has a volume of 315 mL. If this bag of chips is transported to Denver (0.775 atm), what will the new volume of the bag be? P1 x V1 = P2 x V2 1x 315 = 0.775x V2 0.775 0.775 V2 = 406 mL
