4) The quantity of heat required to change an object's temperature by exactly 1 degreesC. 5) This is a material that allows heat/electricity to transfer.
6) This is a measure of the quantity of matter.
8) Random kinetic energy possessed by objects in a material at finite temperature. An object that feels hot has a lot of this.
9) This is a group of elements with few valence electrons that conducts heat and electricity.
10) This is a measure of the average kinetic energy of a substance.

- Down
1) The quantity of heat, in joules or calories, required to raise the temperature of 1 gram of a substance 1 degreesC.
2) This is a material that does not allow heat to transfer.
3) Equipment used to measure the temperature of an object.
7) The transfer of thermal energy between two bodies which are at different temperatures. The SI unit for this is the Joule. Generally considered the raising of temperature due to thermal energy.

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.

good luck: )
