Soojusvõime

Soojusvõime, also known as heat capacity, is a physical property of matter that describes the amount of heat energy required to raise the temperature of a substance by one degree Celsius or Kelvin. It is an extensive property, meaning it depends on the amount of substance present. A larger amount of substance will require more heat to achieve the same temperature change compared to a smaller amount. The unit of measurement for heat capacity is joules per Kelvin (J/K) or joules per degree Celsius (J/°C).

The concept of heat capacity is crucial in thermodynamics and has practical applications in various fields, including engineering and material science. For instance, understanding the heat capacity of different materials helps in designing efficient heating and cooling systems or in selecting appropriate materials for thermal insulation. Substances with high heat capacity can absorb or release large amounts of heat with minimal temperature change, making them useful for applications where temperature stability is important. Conversely, materials with low heat capacity heat up and cool down quickly.
