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.
Calculate the percent error if the accepted value for specific heat for this metal is 0.289 J/gÂ°C. A 46.2 gram sample is heated to 95.4Â°C and then placed in a calorimeter containing 75.0 grams of water at 19.6 Â°C.The final temperature of the metal and water is 21.8 Â°C.Calculate the specific heat of the metal, assuming that all the heat lost by the metal is gained by the water. 46.2 gram sample is heated to 95.4Â°C and then placed in a calorimeter containing 75.0 grams of water at 19.6 Â°C.
