Witryna4 cze 2024 · Specific heat is the amount of heat energy required to raise the temperature of a body per unit of mass. Specific heat is also known as specific heat capacity or mass specific heat. In SI units, specific heat (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin. WitrynaThe specific heat capacity of water is 4.182Jg°C, 4184.0Jkg°C, or 1 calorie (cal). Water has a very high heat capacity compared to other substances. So, it takes more energy to raise the temperature of water by 1 degree than other substances. This also means that water will retain heat better than other substances.
