What is the movement of the fluid called?
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
What term is used for heat transfer because of te movement of a gas?
Convection is the transfer of heat through the movement of a fluid, whether liquid or gas.
How can heat transfer through matter?
Hot matter and cold matter differ by the kinetic energy the atoms/molecules have. Temperature (as measured on the absolute temperature scale) is proportional to the average kinetic energy of the particles in a material.Normally we classify movement of heat according to three processes, thermal conduction, radiative transfer and convection.Heat transfer by Convection occurs in a fluid because it moves and the heat energy contained in the fluid moves with it. This is very important in home insulation and the main reason we insulate walls with fibers to inhibit motion of the air. Radiative transfer of heat occurs when the hot object emits electromagnetic radiation (light) and that electromagnetic radiation carries its energy elsewhere. We can see light energy that came from the sun or even a light bulb, but there is much more energy at longer wavelengths in the infrared part of the spectrum that we can't see. Radiative energy travels through materials (like air) that are transparent, or nearly so, for the particular part of the spectrum carrying the heat. (The distribution of energy emitted as light changes with the temperature of the object doing the emitting which is why we say something is "white hot" meaning it is at a high temperature.)It is heat transfer through conduction that we observe when we say heat travels through a solid body. If one part of an object it hotter than another, the molecules in that part have more kinetic energy. If left undisturbed, heat energy in a hot spot gradually spreads out into the whole object through thermal conduction of heat. Thermal conduction is nothing more that the energetic particles having collisions with their less energetic neighbors and thereby passing on some energyto them. The process happens many millions of times a second between neighboring molecules so only small amounts of energy need transferred from a "hot" molecule to a cooler neighbor for the over all process of neighbor to neighbor transfer to effectively carry that energy from a hot spot to cool spots. Eventually, the temperature of an isolated object will become uniform through this process of intermolecular energy transfer which we recognize as thermal conduction.
Does air moves toward warm air?
In simple, but technically incorrect terms: It rises. In more technical terms: Heat does not rise, heat is defined as transfer of thermal energy - it is a process, not something which can itself be moved (much like electricity is a process of movement of electrons). In convection heat occurs because when things gain thermal energy they expand, so their density increases, so the colder parts of a fluid above them effectively fall through them, pushing the warmer parts upwards.
What is the transfer of therma energy by the movement of fluid?
Transfer of thermal energy by the bulk movement of fluid is the heat transfermechanism of convection.
What is transfer of thermal energy by the movement of a fluid?
This is called convection. One part of the fluid is heated and when it moves to a region of less energy it gives up some heat.

When you touch a hot plate the transfer of heat from the plate to your hand is called .?
conductionHeat is transferred to your hand from a hot object you are touching through thermal conduction.Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection.Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration.Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid.Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two.
Why do particles of matter transfer thermal energy?
Matter is needed to transfer thermal energy by conduction and convection. Conduction happens through a substance when there is a difference in thermal energies between regions. Convection is the movement within a fluid caused by hotter material to rise and colder material to sink and transfer heat.
Temperature is the transfer of thermal energy from one object to another?
The transfer of thermal energy when particles of a fluid move from one place to another is convection. Temperature is a measure of how hot or cold an object is compared to a reference point.Another AnswerNo. Heat (the term, 'thermal energy', is obsolete) is defined as 'energy in transit from a warmer body to a cooler body'. So a temperature difference is necessary for heat transfer to take place.It is not heat it is convection.
When a component becomes hot how does heat transfer from where it is in contact with the plate to the rest of the plate?
Heat is transferred to your hand from a hot object you are touching through thermal conduction. Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection. Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules.
