calorimetry

 [kal″o-rim´ĕ-tre]
measurement of the heat eliminated or stored in any system.
direct calorimetry measurement of the amount of heat produced by a subject enclosed within a small chamber.
indirect calorimetry measurement of the amount of heat produced by a subject by determination of the amount of oxygen consumed and the amount of carbon dioxide eliminated.

cal·o·rim·e·try

(kal'ō-rim'ĕ-trē),
Measurement of the amount of heat given off or absorbed by a reaction or group of reactions (as by an organism).

cal·o·rim·e·try

(kal'ŏr-im'ĕ-trē)
Measurement of the amount of heat given off by a reaction or group of reactions (as by an organism).

calorimetry

Measurement of the energy value of foodstuffs or the energy expenditure of a person. Food is burnt in a special chamber called a BOMB CALORIMETER and the heat rise measured. Human energy expenditure can be measured indirectly by assessing the amount of oxygen consumed.

cal·o·rim·e·try

(kal'ŏr-im'ĕ-trē)
Measurement of the amount of heat given off by a reaction or group of reactions (as by an organism).
