Web1st law of thermodynamics is based on the principle of conservation of energy, and it basically says that the change in total internal energy of a system is equal to the energy absorbed as heat minus the energy lost from doing work. ΔE = Q - W. ΔE is the same thing as ΔU, which is change in internal energy.
