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.
Measuring the specific thermal capacity (also called the 'specific heat capacity') of aluminium, including the use of a cooling correction. For each group of students. Immersion heater, 12 V 100 W (older, 60 W types will do) Aluminium calorimeter with holes for heater and thermometer (see discussion below)
