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.
Example #2: Determine the final temperature when 10.0 g of aluminum at 130.0 Â°C mixes with 200.0 grams of water at 25.0 Â°C. There is no difference in calculational technique from Example #1. Please note the starting temperature of the metal is above the boiling point of water.
