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.
Science GCSE Coursework What affects the rate of heat transfer through an Aluminium can? There are three main factors of heat transfer (heat loss). These are: > Conduction- of heat mainly happens in solids i.e. metals. Conduction of heat is the process where vibrating particles pass on their extra vibrations of energy to neighbouring particles.
