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.
When a piece of aluminum weighing 35.7 grams, and at a temperature of 81.9 o C, is placed. in a calorimeter containing 75.0 grams of water at 24.9 o C, the temperature increases to 28.3. o C. If the specific heat of the water is 4.18 J/g â¢ K and the specific heat of the aluminum is.
