How does infrared radiation affect humans?
We experience it as heat.
A material that reduces the flow of heat by conduction convection and radiation is?
A thermal isolator.
How can heat radiation be prevented?
by insulating heat producing system from 4 sides will reduce radiation. and that insulator should be in dark colour, because we know that dark bodies absorb radiations easily.
How is heat transfered by radiation different from conduction and convection?
Radiation does not need any material medium to transfer energy where as the other two conduction and convection need a material medium to perform.
Why does the colour of something affect the amount of heat it gains?
Because the colour of something affect the amount of heat absorption by radiation. Black bodies absorb the most radiation while white bodies absorb the least radiation. (reflecting heat radiation)Answer 2:The color of an object depends on what color of light it reflects back. A red object absorbs all other colors and reflects red light to your eyes. White is all colors and black is no light. You've probably heard wearing black in the sun makes you very hot. This is because there is no light being reflected back, it's all absorbed. A white shirt is cooler because it reflects all light colors and absorbs much less. Now, what determines the color that is reflected is the atomic composition of the object. Different colors of light have different frequencies, and certain atoms and materials absorb only certain frequencies of electromagnetic radiation (light). So it's not really the color that determines the amount of heat absorbed, it is the composition of the material that determines both the colors of light that are absorbed and thus, how much energy is absorbed. The color is a secondary effect perceived by you, it really doesn't control the heat absorption, it's a result of the atomic structure of the material.
Does the amount if heat radiation absorbed by a surface depend only on its colour?
no

Is radiation heat?
No... radiation is the movement of waves and particles, and influence of movement upon all other matter around it or in it's path... What happens though, is that it causes (excellerates) the atoms in any material it encounters (and that material becomes hot, the greater the radiation, the greater and more violently it will be heated)...
What is the heat capacity of dark colors vs light colors?
The darkness or lightness by itself doesn't affect the heat capacity, only how easily radiation will be absorbed - and emitted.The darkness or lightness by itself doesn't affect the heat capacity, only how easily radiation will be absorbed - and emitted.The darkness or lightness by itself doesn't affect the heat capacity, only how easily radiation will be absorbed - and emitted.The darkness or lightness by itself doesn't affect the heat capacity, only how easily radiation will be absorbed - and emitted.
How do changes in heat energy affect the density of earths mantle material?
How do changes in heat energy affect the density of earths mantle material
Why does a black colour absorb more heat?
because its a good emitter/absorber of radiation
What are the ways by which heat is transferred from one material to onother?
Conduction, Convection, or Radiation
What do you call a material that reduces the flow of heat by conductionconvection and radiation?
a thermal isolator
A material that reduces the flow of heat by conduction convection and radiation is?
A thermal isolator.
What are some charactaristics from the sun that have affect on earth?
Light, heat, radiation

WHY inner bottle's outer body of a thermous flask is made up of silver in colour?
because sliver colour absorbs maximum heat radiation. that's why it is of sliver colour.
