The graph shows how the solubiliites of two salts change as water temperature changes. Which two statements are true based on the relationships shown in the graph? A. More potassium nitrate dissolves as the temperature of water decreases
B. At higher temperatures, more potassium nitrate than sodium chloride dissolves in water.
C. At all temperatures, more potassium nitrate than sodium chloride dissolves in water.
D. The solubility of sodium chloride changes less with temperature than the solubility of potassium nitrate.

ITS OVERDUE PLEASE HELP!!!

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

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.

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
