What type of heat energy dose a telly give out radiation or convection or conduction?
Radiation, convection and conduction are not different types of energy, but different methods of conveying the energy. The heat energy from a television set will be conveyed mainly through conduction and convection, ie the casing will heat up through conduction and the air above the televison will become heated through convection. There will be heat transmitted by radiation, but this will quickly encounter air molecules which will then add to the convection effect.
Which forms of heat transfer are described above as helping to create a sea breeze?
Two forms of heat transfer help create a sea breeze are conduction and convection. Another form of heat transfer help create a sea breeze is radiation.
Does body heat use convection conduction or radiation?
in fact all:) since convection is a kind of conduction, which means heat is transferred via motion of the air surround us, we loose heat by conduction with our clothes, convection from our uncovered skin areas and radiation the same
Does double glazing prevent conduction or convection?
Both - Conduction- the gap of air between two panes of glass. Convection - by sucking the air out However, don't say it will be 'prevented' (especially in an exam as you may lose marks!) it is only slowed down,
Is a heater a conduction or convection?
Heater Is neither Conduction nor Convection... The Questions seems to be wrong... If you ask Whether the heat given by a heater is lost by conduction or Convection, then the answer is: YES! In a heater the heat is lost by all three processes namely Conduction , Convection and Radiation.
How do conduction convection and radiation affect the movement and temperature of air near the ocean?
Conduction, convection and radiation affects the movement and temperature of air near the ocean. Conduction causes difference in temperatures. For example, during a hot day, land heats up more quickly than water. Water is a better conductor of heat. The air near the land's surface is heated due to conduction and radiation. It expands and rises since it is lighter than surrounding air. This is called convection. To replace the air that rose, the air from the sea's surface blows to land.
What is the circular movement of cool air rising and warm air sinking?
Convection! I know this was on your science ws cause it was on mine too :)
Is heating of air touching a hot surface conduction or convection?
convection
What are the two dominant mechanisms of heat transfer around the world?
Movement of heat around the earth happens mostly via conduction and convection. Conduction involves the transfer of heat as kinetic motion of molecules through most any substance, mostly visible in red-hot metals. Convection involves the movement of air as it heats unevenly, causing warm air to rise and cool air to fall.
What are the three mechanisms by which heat is transferred through the Earth's system?
convection (from the movement of fluids), conduction (through solids), and radiation (through air and space).

Is hair dryer an example of conduction or convection?
A hair dryer is an example of convection. Convection refers to the transfer of heat through the movement of fluids or gases. In the case of a hair dryer, the heat is generated by an electric element and is then transferred to the surrounding air. The heated air is then blown out of the hair dryer and onto the hair, drying it by convection. Conduction, on the other hand, refers to the transfer of heat through direct contact between objects. An example of conduction would be touching a hot stove and feeling the heat transfer to your hand through direct contact. It is important to note that both convection and conduction can occur simultaneously in many heat transfer situations. For example, a hair dryer may also transfer heat to your hair through conduction as the hot air comes into contact with your hair.
What is the upward movement of warm air and the downward movement of cold air?
Conduction
Is a hot air balloon a conduction convection or radiation?
how am i supposted to know
Is the pattern of warm air rising and cool air sinking is known as the conduction current?
It's known as a convection current not a conduction current :)
What are some examples of conduction radiation and convection?
Radiaton- the sun rays conduction putting a pan on a hot stove convection- hot air rising cooling and falling
