WebThe specific heat c is a property of the substance; its SI unit is J/ (kg ⋅ K) or J/ (kg ⋅ °C ). The temperature change ( Δ T ) is the same in units of kelvins and degrees Celsius (but not degrees Fahrenheit). Specific heat is closely related to the concept of heat capacity. WebUniversity of Victoria. There is a useful and important distinction in thermodynamics between extensive (or “capacitive”) and intensive quantities. Extensive quantities are those that depend upon the amount of material. Examples would include the volume, or the heat capacity of a body. The heat capacity of a body is the amount of heat ... Webentropy of a black hole shows that as a black hole loses mass through evaporation its entropy will decrease.
