False radiation is the transfer of energy through space.
No that is convection. Radiation is transfer of heat by air.
False. The transfer of heat by the movement of heated fluid is convection. Radiation is the transferal of heat via infrared rays.
No, energy is usually transferred in fluids by convection.
Have a great day !!! :)
convection (from the movement of fluids), conduction (through solids), and radiation (through air and space).
Energy is transferred through moving currents of warmer air or liquid.
Mode of energy transfer in fluids is convection.
Energy transfer by convection is primarily restricted to fluids. One of the significant modes of heat transfer is convective heat transfer.
Conduction.
radiation
No, the principle method of heat transfer in fluids is convection, as the most energetic molecules rise towards the surface and the least energetic sink. Radiation is most significant for objects which are very hot, even glowing.
Conduction:- Conduction is the transfer heat from a hotter to a colder body by vibrating. Convection:- Is the main heat transfer mechanism in fluids. Radiation:- Radiation is the process of particles transferring heat through matter or space.

It can be transferred in three ways: Conduction, convection, and radiation. Conduction is transfer through a substance by contact between atoms. Convection is transfer in a gas (air) by causing air currents due to density effects. Convection can also happen in fluids like water. Radiation is by electromagnetic waves at the infra-red frequencies.
Heat transferred in convection occurs through movements of fluids.
the process whereby heat moves from one body or substance to another by radiation, conduction, convection, or a combination of these methods. Heat transfer flows from a body with high energy (higher temperature) to lower energy (lower temperature).
Thermal energy can be transferred from one body, usually hotter, to a second body, usually colder, in three ways: Thermal conduction, convection, and radiation.1. Thermal conduction: Transfer of heat energy resulting from differences in temperature between adjacent bodies or adjacent parts of a body.In the absence of a heat pump, the energy will flow from a region of higher temperature to a region of lower temperature. The transfer of energy occurs as a result of collision among the particles of the matter involved. The rate of transfer of energy is proportional to the cross-sectional area of contact and to the difference in temperature between the two regions. A substance of high thermal conductivity, such as copper, is a good thermal conductor; one with low thermal conductivity, such as wood, is a poor thermal conductor.2. Convection: Process by which heat is transferred by movement of a heated fluid such as air or water.Most fluids expand when heated. They become less dense and more buoyant, and so rise. The heated molecules eventually cool, become more dense, and sink. This repeated process sets up convection currents that account for the uniform heating of the air in a room or water in a kettle. Air convection can be forced by a fan, and water convection by a pump. Atmospheric convection currents can be set up by local heating effects such as solar radiation or contact with cold surfaces. Such currents are usually vertical and account for atmospheric phenomena such as clouds and thunderstorms.3. Radiation: Process by which energy is emitted from a source and propagated through the surrounding medium, or the energy involved in this process.Radiation consists of a flow of atomic or subatomic particles or of waves.Thermal or heat energy can be transferred in three ways.1. Conduction, when 2 objects are touching.2. Convection, which is the movement of molecules in a fluid.3. Radiation, electromagnetic radiation like infra red.If it is a solid to another it is by conduction. If it is a liquid or a gas to another it is by convection. If it is by light then it is by radiation (e.g. the sun's rays and heat)

No
No, HIV can be transferred with bodily fluids such as blood and semen.
