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.
Place the thermocouple tip in the center of the aluminum piece and fold once more. Fold the sides so that the foil clings to the thermocouple tip. To Test Oven Temperature. 1. Place the weighted thermocouple probe in the center of the oven cavity, centered from front to back, top to bottom, and side to side.
