In experiment b you will, using a light bulb, convert electrical energy into heat from which you will determine joule's constant again for this process you will then repeat this experiment but now allowing some of the energy to escape in the form of light.

Below is an excerpt from james p joule, “on the mechanical equivalent of heat,” philosophical transactions of the royal society, 140:61-82 (1850) for a long time it had been a favorite hypothesis that heat consists of “a force or power belonging to bodies,” but it was reserved for count rumford to make the first experiments decidedly in favor of that view. Do this and determine which of the two experiments provided the more accurate result mechanical equivalent of heat / j apparatus, instruction sheets. Please view this simulation of james prescott historic experiment from scortual mechanical equivalent of heat to understand his experiment better by conducting a series of experiment joules found that when the falling weights lost 4186 kj of energy the temperature of water increased by one degree celsius. Mechanical energy can be converted into heat, and heat can be converted into some mechanical energy this important physical observation is known as the mechanical equivalent of heat this means one can change the internal energy of a system by either doing work to the system, or adding heat to the system.
