Ne Feedback: See Chapter 09 Question 5 of 25 4.0/ 4.0 Points A small bubble rises from the bottom of a lake, where the temperature and pressure are 4°C and 3.0 atm, to the water's surface, where the temperature is 25°C and the pressure is 0.95 atm. Calculate the final volume of the bubble if its initial volume was 2.1 mL. A. 22.4 mL B. 7.1 mL C.
0.72 mL D. 6.2 mL E. 41.4 mL Feedback: See Chapter 09 Question 6 of 25 0.0/ 4.0 Points A gas sample is heated from -20.0°C to 57.0°C and the volume is increased from 2.00 L to 4.50 L. If the initial pressure is 0.109 atm, what is the final pressure?
E. 0.0632 atm Feedback: See Chapter 09 Question 7 of 25 4.0/ 4.0 Points A glass column is filled with mercury and inverted in a pool of mercury. The mercury column stabilizes at a height of 752 mm above the pool of mercury. What is the pressure of the atmosphere?
