Is a smoothie a suspension?

On separation: Smoothies are suspensions of foods with different densities, so when you let them sit, they’ll separate, with the heavier particles settling towards the bottom.

Is sugar and water a suspension?

Answer choice (C) states that the sugar and water would form a heterogeneous mixture called a solution. The particles dissolved in a solution are also smaller than the dispersed particles of colloids and suspensions. When adding sugar to water, sugar is the solute and gets dissolved by water, which is the solvent.
