One of the major effects of heat transfer is temperature change: Heating increases the temperature while cooling decreases it. WebIn the SI system, the specific heat is numerically equal to the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00°C. The SI unit for specific heat is J/(kg × K) or J/(kg × °C). (Recall that the temperature change ΔT is the same in units of kelvin and degrees Celsius.) it has the largest market share at present
