The amount of heat equivalent to 200 Joules depends on the type of energy being measured. For example, in the case of calories, 850 Joules is equivalent to 200 calories. In terms of work energy, 200 Joules of heat is equivalent to the work output from peddling a bicycle on level ground.
Thermodynamics is a branch of physics that deals with the energy of a system and its associated processes. In a thermodynamic process, 200 Joules of heat is given to a gas and 100 Joules of work is also done on it. The change in internal energy of the gas is a result of this thermodynamic process.
Besides thermodynamics, Joule used his namesake law to explain the mechanical equivalent of heat. He concluded that work done in applying a force to an object over a distance is equivalent to the amount of heat generated in the process. This was a breakthrough moment in the field of energy studies, as it explained so much about how energy can move between different systems.
Overall, the amount of heat equivalent to 200 Joules varies depending on the type of energy being considered. In terms of thermodynamics, 200 Joules of heat results in a change in internal energy of the system. In terms of mechanical equivalents, 200 Joules of heat is equivalent to the work done in applying a force to an object over a distance.
