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.
firstly......aluminum is a metal by itself in nature.... aluminum is considered as a metal for the following reasons: 1 - aluminum is a solid at room temperature and has a relatively high density. 2- aluminum can be hammered into sheets and drawn into wires.most importantly, 3 - aluminum is a very good conductor of heat as well as electricity. All the above properties belong to metals; hence aluminum is considered as a metal.irstly......aluminum is a metal by itself in nature.... aluminum is considered as a metal for the following reasons: 1 - aluminum is a solid at room temperature and has a relatively high density. 2- aluminum can be hammered into sheets and drawn into wires.
