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.
Solving for the Final Temperature when Metal is dropped in water. Determine the final temperature when a 25.0g piece of iron at 85.0 C is placed into 75.0grams of water at 20.0 C. The specific heat of iron is 0.450 J/g C. The specific heat of water is 4.18 J/g C. Highlight Answer Below. -qmetal=qwater -(mCDT)=mCDT -(mC(Tf-Ti))= mC(Tf-Ti).
