Which of the following can be attributed to water's high specific heat? A lake heats up more slowly than the air around it. Sugar dissolves in hot tea faster than in iced tea. O Oil and water do not mix well. O Ice floats on water. Question 3 Which of the following statements is true for water in its liquid state? It is nonpolar. O It is less dense than ice. . O It has a specific heat lower than most other substances. O It has a heat of vaporization higher than most other substances. Question 41 Which answer best describes why does ice float in liquid water? The high surface tension of liquid water keeps the ice on top. The crystalline lattice of ice causes it to be denser than liquid water. The ionic bonds between the molecules in ice prevent the ice from sinking. O Stable hydrogen bonds keep water molecules of ice farther apart than water molecules of liquid water. Question 5 Three moles of the compound in the figure would weigh how many grams?
