Thermodynamics is a branch of physics that studies the relationship between heat, energy, and work. It explains how these factors interact and change in different systems.
Flow processes in thermodynamics refer to the transfer of heat and/or work between a system and its surroundings. This can occur through various methods such as conduction, convection, and radiation.
The first law of thermodynamics, also known as the law of conservation of energy, states that energy cannot be created or destroyed, but can only be transferred or converted from one form to another.
The second law of thermodynamics states that the total entropy of a closed system will always increase over time, and that it is impossible to convert heat completely into work without some energy being lost as waste heat.
The three main types of thermodynamic processes are isothermal, adiabatic, and isobaric processes. Isothermal processes involve constant temperature, adiabatic processes involve no heat transfer, and isobaric processes involve constant pressure.
