Heat Transfer 2. The audio and video are not syncd starting around 2430. The flow of heat from one body to another without direct contact.
2 2 2 2 were c k is the thermal diffusivity. The transfer of heat energy caused by a phase change such as boiling or condensing is also eferred to as a convective heat transfer process. The second law of thermodynamics states that heat transfers from an object of a higher temperature to that of a lower temperature.
What happens when a liquid or a gas changes phase is described below.
The study of transport phenomena concerns the exchange of momentum energy and mass in the form of conduction convection and radiation. The study of transport phenomena concerns the exchange of momentum energy and mass in the form of conduction convection and radiation. The higher energy atoms and thus higher temperature move toward the lower energy atoms lower temperature in order to maintain equilibrium known as thermal equilibrium. From the thermodynamic point of view heat flows into a fluid by diffusion to increase its energy the fluid then transfers advects this increased internal energy not heat from one location to another and this is then followed by a second thermal interaction which transfers heat to a second body or system again by diffusion.
