What state of matter is jelly?

Jelly is actually a semi rigid structure suspended in a liquid, which we call a “Colloid”. Jelly is usually made of gelatin, which is a protein. And protein, as we all know is a solid at room temperature. read more

States of matter are distinguished on various basis. Intermolecular Force of attraction, appearance, boiling point, melting point and many more. So, basically Jelly is a solid with water filled in it i.e. it is a Semi-Solid. We just know 5 states of matter that are discovered by scientists. read more

The state of matter of jelly depends on the temperature and protein content. Enough protein will trap all of the water molecules and become rigid. Until that point, jelly will still flow (albeit slowly) and is a liquid. read more

But the states of matter don't account for non-Newtonian fluids, which is what jelly is. This is a substance that has a different viscosity dependant on how much pressure is applied to it. Oobleck, one of the better-known non-Newtonian fluids. read more
