How does a vacuum bottle keep food hot or cold?
The main idea is to reduce the heat transfer out of the vacuum bottle, or into it. A vacuum greatly reduces the transfer of heat by conduction and convection, while the mirror reduces heat transfer by radiation.
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 does a thermos reduce heat transfer using convection?
A thermos reduces does not reduce heat transfer using convection, it reduces heat transfer BY convection. This is because there is a vacuum between the container of the liquid and the outer shell off the thermos. This means that no fluid will go round the inside conducting heat one way or the other. Hope this helped
Which type of thermal energy transfer does a foil wrapping reduce the most?
Conduction (Apex)
Does Floor Insulation reduce conduction convection or Radiation?
Consider for a moment how each form of heat energy is transmitted.Conduction requires contact, physical connection between the heat source and the conducting material and the receiver. A conventional electric stove element is a good example of this. As the floor is not floating in air, some conduction of heat does occur, it is difficult to insulate from completely, but the transfer is negligible.Convection is the transfer of heat via a fluid matrix. Think air conditioner coil here. Another example of convection transfer is seen in a convection oven where the fluid matrix is heated air.Radiation is the transfer of any form of energy by excitation of atoms or molecules. A microwave or the infrared heat energy of the sun are good examples of this. However, occasionally radiation doesn't need medium for transfer.In many case heat is transferred through combinations of two or even the three heat transfer modes: conduction, convection, and radiation.Homes are insulated to prevent conduction of heat or cold by contact with heated or cooled air.
Does closing a door at home on a cold night reduce convection radiation or conduction?

Does loft insulation reduce heat loss by conduction convection or radiation?
Insulation reduces heat loss by replacing air space with a less conductive material (insulation). Therefore the answer is conduction.
How garments can be designed to reduce the transfer of heat by convection?
clothes can be made to reduce convection by making the air tighter so convection currents can't occur or if a material is shiny heat and light will reflect off it instead of absorbing it
How does a thermos flask reduce heat loss by convection?
A vacuum between two glass sheets will greatly reduce heat loss through convection, and also through conduction. The fact that the glass is coated (to convert it to a mirror) also reduces the loss by radiation.
How does a vacuum flask reduce the rate of energy transfers?
Conduction and convection are reduced by the vacuum between the two glass layers.Radiation is reduced by the mirror plating.
How does a thick woolly jumper reduce energy transfer by conduction converstion?
the answer is conduction because convection is distrbribution of heat
