1. Specific Heat of Granite: Granite is a type of igneous rock composed of minerals like quartz, feldspar, and mica. The specific heat of granite is relatively low compared to water and sand. It typically ranges between 0.79 and 0.84 joules per gram per degree Celsius (J/g/°C). This means that a significant amount of energy is required to raise the temperature of granite.
2. Specific Heat of Rock Sand: Rock sand is a granular material composed of small particles of rocks and minerals. The specific heat of rock sand varies depending on the composition of the sand. However, in general, it is lower than that of water. The specific heat of rock sand typically falls between 0.19 and 0.25 J/g/°C.
3. Specific Heat of Water: Water has a remarkably high specific heat compared to most other substances. Its specific heat is approximately 4.18 J/g/°C. This means that a relatively small amount of energy can cause a significant increase in the temperature of water. The high specific heat of water contributes to its role in regulating Earth's climate and the functioning of various aquatic ecosystems.
Therefore, water has the greatest specific heat among granite, rock sand, and water. Its ability to absorb and release energy efficiently makes it an important component of Earth's natural processes and human applications.
