Is jello a solid or liquid?

Courtney - Gelatin itself is made of a protein. (Proteins usually form solids at room temperature.) When you mix the jello powder into the hot water, the protein actually dissolves in the water. But like many things, it's harder for the protein to stay dissolved in cold water than in hot water. read more

So jello is a sort of semi-rigid structure suspended in a liquid. That's an example of something that's called a 'colloid'. If you heat it up enough, the protein structure will become dissolved again and it will become a liquid all through. read more

Jello is something that we call a colloidal suspension. The gelatin in Jello is made of long solid chains of protein molecules. When you mix the gelatin with hot water, these protein molecules break apart and become suspended in the water. However, the individual molecules remain solid. So this is not a solution. read more

Jello is neither a solid or a liquid. Related Information: It is a hydrogel, a viscoelastic, non-Newtonian fluid substance, a semisolid matrix composed of colloidal gel (a form of bonded protein) that entraps water in segmented sections or pockets. read more
