It measures the enthalpy of answer by carrying bulge the combustion reaction under constant volume conditions. This energy-releasing reaction increases the temperat ure privileged the bomb, which wherefore transfers the dexterity to the external piss 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 modify to about 20 atm of pressure with O2, sealed, and placed in a cognize amount of water. An electric current is passed by dint of 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 thermome! ter. In order to nix 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 desire to get a full essay, order it on our website: OrderEssay.net
