D law of thermodynamics
In his book, "A New Kind of Science(opens in new tab)" (Wolfram Media, 2024), Stephen Wolfram wrote, "Around 1850 Rudolf Clausius and William Thomson (Lord Kelvin) stated that heat does not spontaneously flow from a colder body to a hotter body." This became the basis for the Second Law. … See more One thing the Second Law dictates is that it is impossible to convert heat energy to mechanical energy with 100% efficiency, according to Britannica(opens in new tab). After the process of … See more The Second Law indicates that thermodynamic processes, i.e., processes that involve the transfer or conversion of heat energy, are … See more Here are some other explanations of the second law of thermodynamics: 1.

So lets suppose we had some system and suppose 80 J of heat flow into the system, and the system does 30 J of work. Would the change in internal energy of the system be expressed as. Δ U = 80 J − 30 J = 50 J. or as.
