Specific Heat Capacity Of A Liquid Method Of Mixtures
Specific Heat Capacity Of A Liquid Method Of Mixtures — the NEET Physics formula with its derivation, variables, validity constraints and worked solver.
Specific Heat Capacity of a Liquid (Method of Mixtures) Determining the unknown specific heat capacity of a substance using a calorimeter under the principle of calorimetry. Principle of Calorimetry: Heat lost by hot body = Heat gained by cold body. Heat gained = (mass of calorimeter its specific heat + mass of water its specific heat) temperature rise. Heat lost = (mass of unknown liquid its specific heat) temperature fall. Equate the two and solve for the unknown specific heat (s). No heat exchange with the surroundings (adiabatic system). No chemical reaction occurs between the liquids. No phase change occurs during the experiment. Uniform temperature is maintained through constant stirring. Neglecting the heat capacity of the calorimeter (water equivalent). Confusing the temperature difference of the cold body with the temperature difference of the hot body. Assuming the final temperature is the average of initial temperatures (only true if heat capacities are equal).
