HECeveer evaporauon and bong (3+2-5)5kg of sugar is dissolved in 250ml of solution. Calculateration anits mass percentage by volume.b)9) Define Tyndall effect.Why is water considered a compound? Mention two points.(2+2+1-5)Define Newton's first law of motion.

Answer»

b. Some facts about water as a compound 1) Its constituents Hydrogen and oxygen are always present in it. 2) Its properties are different from its constituent elements(hydrogen and oxygen) 3) Its constituents cannot be separated by simple physical means but requires chemical methods and it has fixed boiling and freezing point.

c. TheTyndall effectis the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible. As with Rayleigh scattering, blue light is scattered more strongly than red light by theTyndall effect.

d. Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces.
