3 questions and I dont know how to answer them.
A long distance runner wants to lower his body temperature after running a 5K race. He picks up two glasses of water. One glass contains only water, the other contains water and ice cubes.
Q. Assuming that the temperature of the environment is 25.0oC, in which glass would the water molecules be moving more quickly? Explain your reasoning.
Q. The runner drinks the water that contains the ice cubes and lowers his body temperature. Explain in terms of exothermic and endothermic processes why the runner was able to lower his body temperature by drinking the water that contained the ice cubes.
Q. The runner takes a second glass of water that contains ice cubes and pours it over his head in order to lower his body temperature even more. In terms of condensation and evaporation, why does the pouring a glass of water that contains ice cubes over his head lower the runners body temperature?
