Question

When we make tea/coffee/lemonade particles of one type of matter diffuse into particle of other. why

Answer 1

While making a solution, we add solute into solvents. These two type of particles can have many types of forces like intermolecular, ionic and Van der Waal forces. Due to these forces, depending on the nature of solutes and solvents, solid particles dissociates into liquid and occupies the free spaces among the particles. For example, in ionic compounds like NaCl, the salt dissociates in Na+ and Cl-, which forms bonds with the water molecules. Also, only polar substances dissolves in polar solvents (Water is a polar substance) and non polar dissolves in non polar (Benzene is non polar)

Answer 2

i think there is no case of diffusion here .. tea particle get into the space btw the particle of water...this is not diffusion
