Which of the following reduces energy loss due to conduction, convection, and radiation? thermos bottle fiberglass insulation plastic handle on a cooking pot foam insulation

Option (a) is the correct answer.

Explanation:

In a thermos bottle there is silver coating inside the bottle which helps in prevention of heat transfer through radiation.

Also, there is vacuum between its double walls which prevents movement of heat through convection.

On the other hand, the glass walls of thermos are thin which helps in preventing the incoming or outgoing of heat through the process of conduction.

Thus, we can conclude that out of the given options, thermos bottle reduces energy loss due to conduction, convection, and radiation.

Thermos bottle is the correct answer

answer; /// i believe that the correct answer is (c)

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
