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.
Determine the energy required to convert 32.1 grams of ice at -5.0 Â°C to steam at 100.0 Â°C. 15. Determine the energy required to raise the temperature of 46.2 grams of aluminum from 35.8 Â°C to 78.1 Â°C. Specific heat capacity of aluminum is 0.089 J/g Â°C.
