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.
Aluminum is one of the most common metals used to make heat sinks. conductivity of Aluminum is a 235 Watts per Kelvin per meter (235 W/mK). the thermal conduction number, and it refers to the materials ability to conduct heat. higher the thermal conductivity of the metal, the more heat the metal can conduct.
