They say their research shows, for the first time, that caffeine, catechols, and chemical-substances called N-alkanoly-5-hydroxtryptamides stimulate molecular mechanisms of stomach acid secretion in human stomach cells.
Page 1 of 7. Specific Heat. Objectives. In this lab you will. â¢ measure the specific heats of aluminum and lead using a calorimeter and the. Vernier Temperature Sensor. â¢ observe how the temperature of your system reaches equilibrium in real time. â¢ plot your data and analyze it using the Vernier Logger Proâ¢ software.
Typically, the specific heat (J/Â°C ) of the calorimeter is determined experimentally. This value is then multiplied by the change in temperature of the solution to calculate qcal for the reaction. qcal = Î´T (Â°C) x heat capacity (J/Â°C) Experiment Overview: The purpose of this experiment is to verify Hessâs Law.
