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 burns at over 4,100 K (6920Â°F), which is why it is used as a component of some solid rocket fuels. When it burns, it produces Al2O3 (alumina). Wow! You can really get some high exhaust gas velocity (and thrust) this way!
