Thermodynamics is a branch of physics which deals with the energy and work of a system. It was born in the 19th century as scientists were first discovering how to build and operate steam engines. Thermodynamics deals only with the large scale response of a system which we can observe and meas...

An adiabatic process is one in which no heat is gained or lost by the system. An adiabatic process may be accomplished by thermal insulation or by making rapid changes in volume so that there is no time for heat to be exchanged. The first law of thermodynamics with Q=0 shows that all the change in i...

The law expresses that energy can be transformed, i.e. changed from one form to another, but cannot be created or destroyed. It is usually formulated by stating that the change in the internal energy of a system is equal to the amount of heat supplied to the system, minus the amount of work performed by the system on its surroundings.
