This paper presents the first law of thermodynamics, and shows what thermodynamics adds to the work—energy theorem from mechanics. This may help 

Energy transfer across a system boundary due solely to the temperature difference between a system and its surroundings is called heat. The first law of thermodynamics relates changes in internal energy to heat added to a system and the work done by a system. The first law is simply a conservation of energy equation: The internal energy has the symbol U. Q is positive if heat is added to the system, and negative if heat is removed; W is positive if work is done by the system, and negative if work is done on the system.

The First Law of Thermodynamics The first law of thermodynamics is an expression of the conservation of energy principle. Energy can cross the boundaries of a closed system in the form of heat or work. Energy transfer across a system boundary due solely to the temperature difference between a system and its surroundings is called heat.
