with a standard table of specific heat capacities to identify the metal (e.g., iron, brass, or aluminum). Note that small deviations are normal due to heat loss to the calorimeter walls and the air during transfer ( 1.4.2 ). laboratornaia rabota 3 po fizike 8 klass
To determine the specific heat capacity of a solid body (typically a metal cylinder) by comparing the heat given off by the body to the heat received by water in a calorimeter.
): Heat the metal body in boiling water. Its temperature will be approximately Quickly transfer the heated metal body from the
The heat balance equation states that the heat gained by the water ( Qgaincap Q sub g a i n end-sub ) equals the heat lost by the metal body ( Qlostcap Q sub l o s t end-sub
): Record the highest temperature reached by the water after the body is submerged. Note that small deviations are normal due to
