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.
In SI units, specific heat (symbol: c) is the amount of heat in joules required to raise 1 gram of a substance 1 Kelvin. Also Known As: specific heat capacity, mass specific heat. Examples: Water has a specific heat of 4.18 J. Copper has a specific heat of 0.39 J.
