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.
This will stoke the fire and help increase the heat. Place the lid on the foundry and let it warm up. Let the foundry heat for about 10 minutes before placing aluminum inside of it. The temperature in the foundry will need to be above 1220 degrees Fahrenheit (660 degrees Celsius). Once the crucible is glowing orange, the foundry is hot enough to melt aluminum.
