Question

Derive the formula for water equivalent ​

Answer 1

Chemical reactions usually accompany with the formation and absorption of energy in the form of heat. The branch of chemical science dealing with the study of heat and energy changes is known as thermodynamics. The heat changes within a specific system can be studied using the device calorimeter. Calorimetry is derived from the Latin term “calor” which means heat, and the Greek term “metry” means to measure, the heat in the system. The recent advance in the calorimetry and electronics helps the user to maintain the samples under proper conditions that can be easily analysed. The Scottish physician Joseph Black, was the first to recognise the distinction between heat and temperature, and is said to be the “Founder of Calorimetry”. It is noted that the credits for modern techniques of calorimetry is given to French chemist Pierre Eugene Berthelot (1827-1907). He studied the problems associated with the heat measurement and constructed the first modern calorimeter. The terms endothermic and exothermic reactions are also are also invented to describe the heat reactions are also his contributions to chemistry.
