It measures the enthalpy of answer by carrying taboo the combustion reaction under constant volume conditions. This energy-releasing reaction increases the temperature privileged the bomb, which thusly transfers the dexterity to the external urine jacket elevator the external temperature.

It is this rise in the water-jacket temperature which is monitored and then back-calculated to obtain energy release by the combustion reaction. 1. Construction of Bomb Calorimeter A weighed sample of substance is placed in contact with an dismissal electrify inside the bomb. The bomb is change to about 20 atm of pressure with O2, sealed, and placed in a cognize amount of water. An electric current is passed through and through a wire to ignite the mixture. As the combustion takes place, the heat evolved raises the temperature of the calorimeter and its surrounding water, as measured by a thermometer. In order to n! ix heat loss from the calorimeter system, some calorimeters are surrounded by a second water bath, whose temperature is incessantly adjusted (by the experimenter) to yoke that of the calorimeter. Thus, the heat transfer between the system...If you demand to get a full essay, order it on our website: OrderEssay.net
