A calorimeter is a scientific instrument used to measure the heat generated or absorbed in a chemical reaction or physical process. We owe the invention of this device to an observation made just before the turn of the nineteenth century by the...

A calorimeter is a chamber, entirely closed from the outside world, in which one can house an animal and record its body heat. It is used to determine the METABOLIC RATE of small animals—calorimeters for use by large animals (including humans)...

A scientific instrument used to measure differences in heat energy during the course of a chemical reaction or process such as combustion. The differences are usually expressed in CALORIES per unit mass of...

A calorimeter is a device used for calorimetry, the science of measuring the heat of chemical reactions or physical changes as well as heat capacity. The word calorimeter is derived from the Latin word calor, meaning heat. Differential scanning...

Plant calorimeter may pick top crops A new, speedy device that measures a plant's metabolic rate may improve on today's time-consuming methods for developing hardier crops. The machine, a novel form of calorimeter, can provide information in an hour for predicting a...

To explain a difference of 0.5 % between the absorbed-dose standards of the National Institute of Standards and Technology (NIST) and the National Research Council of Canada (NRCC), Seuntjens et al. suggest the fault lies with the NIST water calorimeter being operated at...
