Heat capacity or thermal capacity is a physical property of matter, defined as the amount of heat to be supplied to an object to produce a unit change in its temperature. The SI unit of heat capacity is joule per kelvin (J/K). Heat capacity is an extensive property. The corresponding intensive property is the … Ver mais Basic definition The heat capacity of an object, denoted by $${\displaystyle C}$$, is the limit $${\displaystyle C=\lim _{\Delta T\to 0}{\frac {\Delta Q}{\Delta T}},}$$ where Ver mais The heat capacity can usually be measured by the method implied by its definition: start with the object at a known uniform temperature, add a known amount of heat energy to it, wait for its temperature to become uniform, and measure the change … Ver mais Most physical systems exhibit a positive heat capacity; constant-volume and constant-pressure heat capacities, rigorously defined … Ver mais • Encyclopædia Britannica, 2015, "Heat capacity (Alternate title: thermal capacity)". Ver mais International system The SI unit for heat capacity of an object is joule per kelvin (J/K or J⋅K ). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same unit as J/°C.
