Vedclass · Answer

(N/A) Matter is anything that has mass,occupies space,and has volume.Properties of solids: $(1)$ They have a definite shape and distinct boundaries. $(2)$ They have a fixed volume and negligible compressibility.Properties of liquids: $(1)$ They do not have a fixed shape but take the shape of the container. $(2)$ They have a definite volume and can flow (fluidity).$(b)$ Observation: The water in beaker $A$ (hot water) becomes coloured faster than the water in beaker $B$ (cold water).Reason: Diffusion is the movement of particles from a region of higher concentration to a region of lower concentration. At higher temperatures,the kinetic energy of the water particles increases,which causes the particles of copper sulphate to diffuse more rapidly throughout the water.
