WebJun 6, 2024 · Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances. … WebWhen you heat the water it expands, which does work against the surrounding pressure. At higher pressure, the expansion takes more work. For example, in heating water from 10 C to 30 C, the density decreases from 999.7026 k g m 3 to 995.6502 k g m 3, so 1 k g of water expands by 2.066 ⋅ 10 − 6 m 3. list of nobel laureates in medicine https://djbazz.net
