1.why does the sky looks blue in daytime and looks red during sunset?2Milk is a mixture of liquid butter fat and water. what kind a mixtures is it?
Answer (1)
The sky appears blue during the day and red during sunset due to how sunlight interacts with the Earth's atmosphere. Milk, being a mixture of liquid butterfat and water, is a colloid. Why the sky is blue during the day:Sunlight is made up of all colors of the rainbow. When sunlight enters the Earth's atmosphere, it collides with tiny air molecules. Shorter wavelengths of light, like blue and violet, are scattered more efficiently than longer wavelengths (like red and orange) due to a phenomenon called Rayleigh scattering. This scattered blue light is what we see when we look up at the sky during the day. Why the sky is red during sunset:At sunset, the sunlight has to travel through a much greater distance of the atmosphere to reach our eyes. This longer path means that most of the blue light is scattered away before it gets to us. The remaining light, which is mostly composed of longer wavelengths like red and orange, is what we see. Milk as a colloid:Milk is a mixture where tiny particles (fat and protein) are dispersed throughout a liquid (water). These particles are larger than individual molecules but small enough that they don't settle out. This makes milk a colloid.
