. What is Calorimetry

Best Answer

We can measure energy changes associated with chemical or physcial processes by an experimental technique called calorimetry. In calorimetry, the process is carried out in an vessel called calorimeter, whcih is immersed in a known volume of a liquid. Knowing the heat capcity of the liquid in which calorimeter is immersed and the heat capacity of calorimeter, it is possible to determine the heat evovled in the process by measuring temperature changes. Measurements are made under two different conditions : 

i. at constant volume, qV

ii. at constant pressure, qp
