A kilogram of aluminum metal and a kilogram of water are each warmed to 75 oC and placed in two identical insulated containers. One hour later, the two containers are opened and the temperature of each substance is measured. The aluminum has cooled to 35 oC while the water has cooled to only 66 oC. Explain this difference.

1 answer

How much heat is in each?
q = mass x specific heat x T

Calculate to see how much heat is in each. The water has MUCH more heat; therefore, the temperature drops less.
