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.
Wood's metal has a slightly higher melting point (near 160F/70C) and is less expensive, but it contains lead. Aluminum melts at about 1221 degrees Fahrenheit, which is a heck of a lot hotter than MY oven goes. My guess is you need special equipment both to melt metals and to handle them afterward. I wouldn't try it at home.
