What is the type of energy transferred to my body in each of the following as either internal In the early 19th century James Joule performed quantitative measurements to compare the amount of mechanical work and heat that would raise the temperature of a known quantity of water by the same amount.

This is the basis of the First Law of Thermodynamics. Before we can start with the first law, it is a good idea to be clear on two important in thermodynamics: the system and the surroundings.

The system is the region of the universe under study while the surroundings include everything else in the universe except the system. Everything that exists, is some form of energy, although there are many different types. Whatever energy is, we cannot create it or destroy it; it can change into different forms, but if we the sum of all the forms of energy, it cannot change.

This is a very powerful concept and where the types of energy do not add up, we look for new forms of energy rather than abandon the concept. In the early versions of the quantum theory, conservation of energy and momentum did not seem to both hold simultaneously. This process of Compton Scattering, where light scatters off an electron and changes energy and momentum. The answer was that light behaves as like particles with a mass which depends on the wavelength.
