Experiment 16 * Archimedes Principle
Any object, wholly or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid
displaced by the object.
This can be expressed mathematically as :
Experiment 15 * Specific Heat
The amount of heat required to change the temperature of an object is is proportional to the
mass of that object. Since this value is specific to the material in question, it is referred to as
the specific heat (or heat capac
