The specific heat of granite is typically around 0.79 J/g·°C. This value can vary slightly depending on the mineral composition of the granite, as granite is not a single mineral but rather a mixture of several minerals such as quartz, feldspar, and mica.
Specific heat is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius. For granite, this means that to increase the temperature of one gram of granite by one degree Celsius, approximately 0.79 joules of energy are needed.
Understanding the specific heat of granite is important in various fields, including geology, construction, and even in cooking when considering the heat retention properties of granite countertops. Overall, granite’s specific heat indicates that it has a relatively moderate ability to store thermal energy compared to other materials.
