- In North America, Lake Huron is covered with ice from December to April; In May, they thaw and float on the surface of the lake. Why is that reason? Please explain2. Why does the temperature of a mixture of ice and water remain constant during melting and freezing?Given that a 10.0 g sample of ice at 0.0 °C melts and then the resultant water proceeds to warm to 20.0 °C, there are two separate processes (dealing with the transfer of heat) that describe that occurrence. What are those two processes?

If so, which one? Is this endothermic or exothermic?In a body of water, the surface tension caused by the attraction between water molecules is strong. Which of the following is a consequence of this property? Water is considered to be a universal solvent. When water freezes, the molecules move farther apart. Only a limited amount of solute can be dissolved in a sample of water. Objects with a higher density than water can be observed floating on water.
