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.
1 Heat the furnace to a temperature greater than the melting point of aluminum. 2  Cut larger pieces of aluminum into smaller pieces and work only with small batches in order to more evenly distribute the heat and allow all of the pieces to melt.esearch the price of aluminum to determine if the process of collecting and melting aluminum is worth the time and effort required for the potential monetary reward. 1  Aluminum is a commodity much like oil, corn, or gold. 2  As with all commodities, the market price for aluminum rises and falls daily.
