The world’s first ice-calorimeter, used in the winter of 1782-83, by Antoine Lavoisier and Pierre-Simon Laplace, to determine the heat generated by various chemical changes. The calculations were based on Joseph Black’s discovery of latent heat. These experiments mark the foundation of thermochemistry.

A calorimeter is an apparatus that measures the amount of energy contained in a particular substance.
