Also record the temperature of the empty flask at that instant. Remove both flasks from the heat and place them in ice water. Record the time it takes for each flask to reach its original room temperature. Record your observations. Explanation Water, when heated, evaporates slowly in comparison to other liquids.
Water also has a high latent heat of fusion .
Latent heat of fusion refers to the amount of heat gained or lost when a substance changes from a solid to a liquid, or a liquid to a solid. When ice is formed, large quantities of heat are given off. The high values of the heat capacity, heat of vaporization, and latent heat of fusion mean that it takes more heat to cause a change in temperature in water than in most other substances. This makes water a strong buffer against both rising and falling temperatures. So its ability to store heat strongly affects our climate.
