What role does water play in keeping temperatures from fluctuating dramatically? A. Wateris an acid, A. Wateracts as a bulfer. C. Wateris a versatile solvent. D. Water has a high heat capacity. 4. If you were to heat 1 cup of water and 5 cups of water on a hot plate at the same temperature, which one would boll first? __ Using your knowledge of hydrogen bonds and the polarity of a water molecule, explain why. __ __ 3 Questions 1. Reference 5C.912.L.18.12 -The Properties of Water benchmark from the top of the handout. Which of those properties of water referenced in the benchmark were you observing in this experiment? __ 2. In the following example ,identify the solute, the solvent, and the solution.Ricardo is thirsty after mowing the grass and decides to come inside and make a glass of sweet tea.He adds sugar to the unsweetened prepared tea and stirs the liquid until all the sugar has disappeared from the pitcher. Solute - __ Solvent - __ Solution - __ Imagine you were given an unknown dry substance and you added it to water and no matter how much you heated up the water or stirred the unknown substance, it wouldn't dissolve in the water. What conclusions could you draw about the types of bonds and charges on the substance because it doesn't dissolve in water? __

Answer

D. Water has a high heat capacity. ### 1 cup of water will boil first. ### High heat capacity. ### Solute - Sugar; Solvent - Unsweetened prepared tea; Solution - Sweet tea. ### The substance likely has nonpolar covalent bonds or lacks charges, making it hydrophobic. Explanation 1. Identify the role of water in temperature regulation Water has a high heat capacity, meaning it can absorb or release large amounts of heat with little change in its own temperature. This property helps stabilize temperatures. 2. Determine which cup of water boils first The 1 cup of water will boil first because it has less mass and thus requires less energy to reach boiling point. Hydrogen bonds in water require significant energy to break, contributing to water's high heat capacity. 3. Identify properties observed in the experiment The high heat capacity of water is observed when heating different volumes of water, as it affects how quickly they reach boiling point. 4. Identify solute, solvent, and solution in sweet tea example Solute - Sugar; Solvent - Unsweetened prepared tea; Solution - Sweet tea. 5. Draw conclusions about an unknown substance not dissolving in water If a substance does not dissolve in water, it likely has nonpolar covalent bonds or lacks charges that interact with water's polarity, indicating hydrophobic characteristics.
