The ability to do work Conserved Made of heat and work A state function values that depend on the state of the substance and not on how that state was reached  Independent of the path or how you get from point A to B. 1. st. law of thermodynamics. Energy may be converted to different forms, but it is neither created nor destroyed during transformations. Energy from chemical bonds is converted to kinetic energy and heat (body and friction from tires). No engine, working in a continuous cycle, can take heat from a reservoir at a single temperature and convert that heat completely to work.. Therefore, no engine can have a greater efficiency than a Carnot engine operating between the same two temperatures.. [4]. Change of phase . . ice. .  . water.  . steam. The Laws of Thermodynamics.

A text book of thermal engineering (R.S. Khurmi, J.K. Gupta). Most natural events involve a decrease in total energy and an increase in disorder.. The energy that was “lost” was converted to heat. . An increase in energy/motion decreases the overall order (organization) of the system..
