Problem
A ceramic coffee mug contains 250mL of hot coffee at an initial temperature of 85°C. The mug is placed in a room at 22°C. After 10 minutes, the coffee temperature has dropped to 65°C. Assuming the coffee cools according to Newton's law of cooling, which states that the rate of temperature change is proportional to the temperature difference between the object and its surroundings, find the temperature of the coffee after 20 minutes total. Take the density of coffee to be approximately equal to that of water: ρ=1.0g/mL.
