Heat transfer: Is the energy exchanged between materials

Heat transfer is the energy exchanged between materials (solid/liquid/gas) as a result of a temperature difference . The thermodynamic free energy is the amount of work that a thermodynamic system can perform. 2）heat既可用作不及物动词，也可用作及物动词。 用作及物动词时，表示“使…变热”“把…加热”，接名词或代词作宾语，也可接双宾语，其间接宾语可以转化为介词for的宾语。 Heat is the form of energy that can be transferred from one system to another as a result of temperature difference. A thermodynamic analysis is concerned with the amount of heat transfer as a system undergoes a process from one equilibrium state to another. What is Heat Transfer in Chemistry? A heat transfer process describes the movement of thermal energy from a hotter object to a colder one due to a temperature difference.
