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.
Problem #4: A 5.00 g sample of aluminum (specific heat capacity = 0.89 J Â°C -1 g -1) and a 10.00 g sample of iron (specific heat capacity = 0.45 J Â°C -1 g -1) are heated to 100.0 Â°C. The mixture of hot iron and aluminum is then dropped into 91.9 g of water at 23.7 Â°C.
