Experiment: Increase of Internal Energy
3B Scientific, UE2030300, Experiment for Heat: Increase of Internal Energy by Mechanical WorkUE2030300 Includes Only:Heat Equivalent ApparatusDigital Multimeter P1035Pair of Safety Experiment Leads, 75 cm, blue, redFeatures:Objective: Verifying the First Law of ThermodynamicsThe experiment is to investigate the increase of internal energy of an aluminium body caused by friction. The increase can be observed by measuring the increase in the temperature of the body, which is proportional to the work done, as the body undergoes no change in the state of aggregation and no chemical reaction occurs. To eliminate the effect of heat exchange between the aluminium body and the environment as far as possible, begin the series of measurements slightly below room temperature and end the series at a temperature slightly above room temperature. The difference below and above room temperature prior to starting the measurements and at the point of concluding them should approximately be the same.For more information, please see Data Sheet.
