Mr. O has a little kiddie pool that holds 120.0 L of water. If his kids are to use it, it's got to be at
least 25°C. lf he has access to l5°C city water from a hose, and 85°C hot water from a hot water
tank, how much of each will he need to keep the kids happy and unhypothermic? (ans: 103 L
cold, 17 L hot)
