This kind of approach is called statistical mechanics and involves applying laws of mechanics to large systems of molecules. Classical thermodynamics is a largely macroscopic theory in which we talk about macroscopic quantities such as temperature, pressure, and volume. This macroscopic theory does not rely directly on our understanding of kinematics and Newton's laws. Instead, we work with a set of principles with a macroscopic focus. If two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other.
Heat flows solely from hot objects to cold objects.
The zeroth law tells us that thermometers are useful devices for comparing different systems. The first law is a statement that the total energy of a closed system is conserved. The second law can be stated in several ways, three of which appear above, and amounts to a statement that thermal energy is made inaccessible for conversion to mechanical work as a result of natural processes. In other words, as a result of walking around, converting the chemical energy in your breakfast into work, you are making some quantity of energy inaccessible for further conversion into work. The long term consequence of the second law may be that the universe will eventually reach a state in which no mechanical work can be done, because all of the energy in the universe will be an an unusable form.
