Determination of Specific Heat Capacity via Electrical Method

Calorimetry Calorimetry is a collection of experimental techniques used to measure energy changes and heat flows associated with chemical reactions and physical changes. The term "calorimetry" comes from the Greek words for heat ("calor") and measure ("meter"). calorimetry is the science or act of measuring changes in state variables of a body for the purpose of deriving the heat Calorimetry is the process of measuring the amount of heat released or absorbed during a chemical reaction The principle of calorimetry states that the heat absorbed or released by a substance or system is equal to the heat gained or lost by the surroundings. Heat capacity Heat capacity is defined as the amount of heat energy required to raise the temperature of a given quantity of matter by one degree Celsius. Heat capacity for a given matter depends on its size or quantity and hence it is an extensive property. The unit of heat capacity is joule per Kelvin or joule per degree Celsius. C = Q/ΔT where C is the heat capacity, Q is the amount of heat energy transferred, and ΔT is the change in temperature. The standard unit for heat capacity in the International System of Units (SI) is joule per kelvin (J/K), which is equivalent to joule per degree Celsius (J/°C). Unit = J/oC Heat capacity influences how quickly a substance heats up or cools down. High heat capacity means a substance resists temperature changes, while low heat capacity means it changes temperature quickly. Specific Heat Capacity The basic equation of calorimetry is Q = mcΔT, where: • q: represents the heat energy absorbed or released. • m: is the mass of the substance. • c: is the specific heat capacity of the substance. • ΔT: is the change in temperature (final temperature minus initial temperature). Unit : J/kgoC Heat capacity is the amount of heat required to raise the temperature of an object by 1°C. Specific heat is the amount of energy required to raise the temperature of 1 gram of a substance by 1°C. Relation between heat capacity and specific heat capacity Heat capacity = Mass of the substance x Specific heat capacity. C = m x
