The atmosphere is affected by convention because convection heats the lower atmosphere. Radiation transfers energy which other gases heat up. Conduction does not impact the atmosphere in these same ways.

How is the atmosphere affected by the convection?
The atmosphere is affected by convention because convection heats the lower atmosphere. Radiation transfers energy which other gases heat up. Conduction does not impact the atmosphere in these same ways.
Which layer is most affected by conduction?
the layer that has convection currents is the mantle
What processes of heat transfer are affected with thermos flasks?
Thermos flasks primarily reduce heat transfer by conduction, convection, and radiation. The vacuum insulation between the inner and outer walls of the flask minimizes heat loss through conduction. The silvered coating on the inner surface reduces heat transfer by radiation, while the narrow neck minimizes heat loss through convection.
Which one conduction convection or radiation is affected by color?
Radiation is the form of heat transfer affected by color. Dark colors absorb more thermal radiation than light colors, so they heat up faster when exposed to sunlight. Light colors reflect more radiation, resulting in lower heat absorption.
How is the atmosphere affected by each of the heat transfer mechanism?
Conduction transfers heat by direct contact with the surface of the Earth, affecting lower atmospheric layers. Convection transfers heat through vertical movement of air masses, creating winds and turbulence in the atmosphere. Radiation from the Sun warms the atmosphere and surface, influencing global climate patterns.
How is rubber affected by radiation convection and conduction?
Rubber can degrade when exposed to high levels of radiation, causing it to become brittle and lose its elasticity. Convection can lead to changes in rubber properties due to temperature fluctuations, but it generally does not have a significant impact. Conduction can affect rubber by transferring heat and potentially altering its mechanical properties, depending on the temperature conditions.
At what spead does transfer of heat take place?
Heat transfer is in three modes. Conduction, convection and radiation. In case of conduction, the speed of transfer depends on the conduction property of the material. In case of convection, the speed of transfer depends on the density of the liquid. In case of radiation, the speed of transfer of heat is at the speed of light in air medium and a little bit less in other denser medium.
How is radiation unique and different from the other two forms of transfer?
Radiation is distinct from conduction and convection as it does not require a medium to transfer heat. Instead, it can occur through electromagnetic waves, such as light or infrared radiation. Radiation is also not affected by the temperature difference between two objects and can travel through a vacuum.
How does conduction and convection are affected by paving over a grass field?
It is harmful and effects the air pollution
How do radiation and conduction compare o each other?
Radiation is the transfer of heat through electromagnetic waves, while conduction is the transfer of heat through direct contact between materials. Radiation can occur even in a vacuum, whereas conduction requires a medium for heat transfer to take place. Radiation is not affected by the medium's conductivity, but conduction is dependent on the material's ability to conduct heat.
How is the atmosphere affected by?
Atmosphere continuously receives radiation. Some like UV are absorbed by ozone.
What is the emissivity of black body?
Emissivity of the black body is 1. And this is probably the reason that the condenser of refrigerator is painted black to loose heat efficiently by radiation ,though there are other modes of heat transfer like conduction and convection which is not affected by colour of the body
