Q: How does the solubility of gases in liquids change with increasing temperature? Read this paragraph and choose the correct option from the provided answers: Effect of Temperature on the Solubility of Gases The solubility of gases in liquids decreases with increasing temperature, as shown inFigure 13.10 "Solubilities of Several Common Gases in Water as a Function of Temperature at Partial Pressure of 1 atm". Attractive intermolecular interactions in the gas phase are essentially zero for most substances. When a gas dissolves, it does so because its molecules interact with solvent molecules. Because heat is released when these new attractive interactions form, dissolving most gases in liquids is an exothermic. Choices: - it increases - it stabilizes - no change - it decreases A:
(A).
it decreases

Q: What is the first digestive organ that food enters? Read this paragraph and choose the correct option from the provided answers: The mouth is the first digestive organ that food enters. The sight, smell, or taste of food stimulates the release of saliva and digestive enzymes by salivary glands inside the mouth. Saliva wets the food, which makes it easier to break up and swallow. The enzyme amylase in saliva begins the chemical digestion of starches to sugars. Choices: - stomach - tongue - esophagus - mouth A:
(A).
mouth
