State first law of thermodynamics , Physics

First law of thermodynamics is stand on the principle of the conservation of power. According to the first law,

ΔQ = W + ΔU      Where,   Δ Q =  heat given to the system

                               ΔU = Change in internal energy of working fluid (confined ideal gas)       

                                  W = Work done by the system

In applying this law special care must be taken in using the sign convention accurately.
