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.
Determine the heat required to convert 62.0 grams of ice at -10.3 Â°C to water at 0.0 Â°C. The specific heat capacity of ice is 2.06 J/g Â°C. 6. Determine the energy required to raise the temperature of 46.2 grams of aluminum from 35.8 Â°C to 78.1 Â°C. Specific heat capacity of aluminum is 0.089 J/g Â°C. 7.nit for heat is J (joules), specific heat is J/g Â°C. NOTE: use must use the specific heat that applies to the physical state of the substance. Specific heat for steam (water vapor) 2.02 J/g Â°C Specific heat for liquid water 4.184 J/g Â°C Specific heat for ice is 2.06 J/g Â°C.
