Thermodynamics,science of the relationship between heat,work,temperature,and energy.Thermodynamics deals with the transfer of energy from one place to another and from one form to another.The key concept is that heat is a form of energy corresponding to a definite amount of mechanical work.thermodynamics - Derivation of heat capacity at constant In thermodynamics,we define heat capacity in terms of internal energy U and enthalpy H,not in terms of heat.In this way,heat capacity is a physical property of the material being processed,and not a function of the process path.Which of the thermodynamic functions (Internal energy This lesson covers the topic of heat capacity,which is a core concept of thermodynamics.We will review the definition of heat and explore how it relates to an object's heat capacity.
