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.
Throw-way aluminum cups are used. To Operate: Set the infinite control to desired test temperature. Pour the material sample into throwaway aluminum cup, place cup in hot pot, insert wire stirrer, set counter to zero, and switch on. After gel occurs, read gel time and discard cup and stirrer.
