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.
Heat Capacity of a Metal. A calorimeter is made using two nested styrofoam cups and filled with 175.0 g of water at an initial temperature of 25.0Â°C. A quantity of water is heated to 100.0Â°C and 25.0 g of aluminum is heated in the boiling water for five minutes. calorimeter is made using two nested styrofoam cups and filled with 175.0 g of water at an initial temperature of 25.0Â°C.
