WebMay 27, 2024 · Picture Courtesy: nutraveller/Pixaba. Land heats and cools faster than water for many different reasons. But one of the main reasons is the difference in molecular composition between land and water. Because of the movements of the molecules, it takes much longer for water to heat up or cool down. However, this is the simple answer, and … WebMar 11, 2024 · Specific heat tells you the amount of energy needed to raise each unit one degree. For example, it takes .417 Joules to raise 1 gram of water 1 degree Celsius. So, water's specific heat is .417 J/C per gram. The specific heat of a material is constant. That means that all pure water has the same specific heat-- .417 J/C.
