Refer to Figure 11.12 to answer these questions: (a) You heat some water to 60 C in a lightweight plastic bottle and seal the top very tightly so gas cannot enter or leave the carton. What happens when the water cools? (b) If you put a few drops of liquid diethyl ether on your hand, does it evaporate completely or remain a liquid? Figure 11.12 Vapor pressure curves for diethyl ether [(C2H3)2O], ethanol (C2H5OH), and water. Each curve represents conditions of T and P of which the two phases, liquid and vapor, are in equilibrium. These compounds exist as liquids for temperatures and pressures to the left of the curve and as gases under conditions to the right of the curve. (See Appendix G for vapor pressures for water of various temperatures.)
Refer to Figure 6.12 and answer the question. Water is sometimes made safe to drink by boiling. Explain why this might not work if you attempted to do it in an open pan on the summit of Mount Everest.
Dissolving 3.0 g of CaCl2(s) in 150.0 g of water in a calorimeter (Figure 5.12) at 22.4 °C causes the temperature to rise to 25.8 °C.

Previous Answers Request Answer % openvellum.ecollege.com FS E Course Home An increase temperature usually increases the solubility of solids and decreases the solubility of gases in water. S An increase in pressure of a gas above a liquid increes the solubility of a gas within that solution and decreases the solubility of solids. F6 X Incorrect; Try Again; 5 attempts remaining You filled in 1 of 4 blanks incorrectly. Henry's law states that the solubility of a gas in a liquid is directly related to the gas pressure above the liquid. The law does not apply to solids, as the pressure does not impact the number of solid…
