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.
Heat the parent metal surface . Heat the surface, not the AlumiWeld. Apply the AlumiWeld to the heated surface. *Use Neutral Flame if using Oxy Ac - Keep Flame In Motion - Never Plunge Into Water - Cool Slowly*. Clean aluminum down to bare metal, getting off all dirt, paint, and coatings.
