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.
By Todd Helmenstine. This worked example problem demonstrates how to calculate the specific heat of a substance when given the amount of energy used to change the substance's temperature.Problem: It takes 487.5 J to heat 25 grams of copper from 25 Â°C to 75 Â°C.y Todd Helmenstine.
