That's because of something called heat capacity. Water has a high heat capacity. In comparison, air has a low heat capacity, so it gets warmer and cooler much faster than water does. At this ...

This causes the calculated specific heat capacity to be higher than for one kilogram (kg) of water alone. The lid on the calorimeter has reduced much thermal energy loss, and the use of cotton ...

Water also has a high heat capacity, which means it holds heat longer and takes more energy to cool it down. Which is why lakes stay warm into the fall, even as air temperatures cool off.

Place equal masses of lead and aluminum in the boiling water and allow them to heat for several minutes. Measure the temperature of the water. Remove the metals and place them in separate beakers ...
