Heat effects of chemical or physical processes can be measured in a calorimeter.
Can someone please paraphrase this to me.... if possible. Heat effects of chemical or physical processes can be measured in a calorimeter. Instruments of widely varying designs are employed to accommodate the large range of experimental conditions encountered. For instance, the heat effects to be measured may range from milliJoules to milliliter, quantities involved from fractions of milliliters to hundreds of milliliters and from milligrams to grams, operating temperatures from below liquid helium temperature (4.2 K) to 2000o C, and...
