thermodynamics

• Thermodynamics is a science that describes how thermal energy is converted from one form to the other and how it affects the matter.
• Thermodynamics is a Greek word which means flow of heat in physical and chemical reactions
• Thermodynamics is a branch of science which deals with study of different forms of energy and their interconversions.
• Thermodynamics is the study of processes in which energy is transferred as work and heat.
• The system is a set of particles we wish to study
• The environment is everything else.
• Heat (Q) is the transfer of energy into or out of the system by a temperature difference.
• Work (W) is the transfer of energy into or out of the system by a force.
• Zeroeth Law (Temperature) – two systems in equilibrium with a third system are in thermal equilibrium with each other
• First Law (Conservation of Energy) – energy can change forms, but is neither created nor destroyed.
• Second Law – Entropy of an isolated system always increases
• Third Law – entropy of a system approaches a constant as temperature approaches absolute zero.
• Thermochemistry – the study of how energy in the form of heat is consumed and produced by chemical reactions.
• Energy – is anything having the capacity to do work or to transfer heat.
• Work – is force x distance.
• Thermodynamics – the study of energy and its transfer from one form to another.
