- The movement of matter during convection is what transfers thermal energy.
- The air or liquid currents help transferring thermal energy through convection as the currents of higher temperature are of less density (lighter) and move upwards while that of less temperature are of higher density (heavier) and move downwards.
- Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids (liquids or gases). Convection is usually the dominant form of heat transfer in liquids and gases.

What happens to particles during the process of convection?
The particles move around from one place to another through the flow of thermal energy during convection.
What are 2 processes for which thermal energy is required during boiling?
convection and radiation
The inside frame of your front door feels cold during the winter is an example of what heat transfer?
convection
What is heat transfer by convection caused by?
Heat transfer during convection heating is simply caused by diffuse expansion through liquid with regard to the force of buoyancy. This phenomenon can be noticed in nature as well as forced in the lab
Does water absorb thermal energy during condensation?
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.

What process causes the warm air to move upward over the land during the day?
convection
How do you beat conduction and convection radiation?
the form of heat transfer in which the energy is transferred from one molecule to another is called conduction. the mode in which the molecules get transported during the heat transfer process is called convention. heating up of sand is conduction and that of water is convention.
Does water absorb thermal energy during condensation?
No, water releases thermal energy during condensation. It absorbs thermal energy during evaporation, which is why the evaporation of sweat cools your skin.
How is heat transferred during stewing?
Conduction between the heat source (stove's burner) and the pot. Convection of the fluids in the pot, to transfer and distribute heat evenly within these fluids. Hope this was helpful
How convection is used?
Convection is just heat transfer by creating currents to move the heat around from a source to where the heat is wanted. This occurs for instance in an oven during cooking, or from radiators in a central heating system.air: The invisible gaseous substance surrounding the earth, a mixture mainly of oxygen and nitrogenMore »
What is a thermal barrier?
A thermal barrier is any protective covering or barrier which inhibits the transfer of heat. For example the space shuttle used a thermal barrier to prevent the astronauts from burning to death when entering the earth atmosphere during re-entry. The thermal barrier reduced the heat caused by the friction of the air passing over the spacecraft to acceptable levels. Without it the shuttle would have burn up and disintegrate. The failure of the thermal barrier was the reason that the Space Shuttle Columbia burned up during re-entry on February 1, 2003.
What is heat conduction?
in heat transfer, conduction (or heat conduction) is the transfer of heat energy by microscopic diffusion and collisions of particles or quasi-particles within a body due to atemperature gradient. The microscopically diffusing and colliding objects include molecules, electrons, atoms, and phonons. They transfer microscopically disorganized kinetic energy. Conduction takes place in all forms of ponderable matter, such as solids, liquids, gases and plasmas.By conduction, as well as by thermal radiation, heat spontaneously flows from a body at a higher temperature to a body at a lower temperature. In the absence of external driving fluxes, temperature differences, over time, approach thermal equilibrium.During conduction, the heat flows through the body itself, as opposed to its transfer by the bulk motion of the matter as in convection, and by thermal radiation. In solids, it is due to the combination of vibrations of the molecules in a lattice or phonons and diffusion of free electrons. In gases and liquids, conduction is due to the collisions and diffusion of the molecules during their random motion. Photons in this context do not collide with one another, and heat transport by electromagnetic radiation is conceptually distinct from heat conduction by microscopic diffusion and collisions of material particles and phonons. In condensed matter, such as a solid or liquid, the distinction between conduction and radiative transfer of heat is clear in physical concept, but it is often not phenomenologically clear, unless the material is semi-transparent. In a gas the distinction is both conceptually and phenomenologically clear.In the engineering sciences, heat transfer includes the processes of thermal radiation, convection, and sometimes mass transfer. Usually more than one of these processes occurs in a given situation. The conventional symbol for the material property, thermal conductivity, is .
