Web2 de may. de 2024 · calorimeter and the temperature is recorded every 10 seconds for 3-5 minutes. Note the temperature (t 3) which remains constant. Calculation: Let water equivalence of a calorimeter = W g Heat lost by warm water= Heat gain by cold water + heat gained by the calorimeter Heat lost by the hot water is = (t 2-t 3) cal. Web12 de sept. de 2024 · The specific heat is numerically equal to the amount of heat necessary to change the temperature of 1.00 k g of mass by 1.00 o C. The SI unit for specific heat is J / ( k g × K) or J / ( k g × o C). (Recall that the temperature change Δ T is the same in units of kelvin and degrees Celsius.)
