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.
3. 216 J of energy is required to raise the temperature of aluminum from 15 o to 35 o C. Calculate the mass of aluminum. (Specific Heat Capacity of aluminum is 0.90 J o C -1 g -1).nswer: 89.0 J/(18.0 g x 25.0 C) specific heat = 0.371 J/g C. Specific Heat Capacity (C or S) - The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity of the substance.
