Is Ketchup a Solid or Liquid?
Dead serious. This is a question that came up during MCAT studying.

neither. Ketchup is a non-newtonian fluid. It exhibits more properties of a solid when there is no force on it but exhibits liquid properties when there is a force (ie squeezing it out of the bottle). Another well known non-newtonian fluid is cornstarch+water but it exhibits different properties.

I think it is a liquid. If glass is a liquid I will believe anything.

Just saw the actual poll. Ya its def a non-newtonian fluid (specifically shear thinning). By the way, the reason you are probably asked this is because BLOOD also falls into this class. The shear thinning properties of blood make difficult to work with on occasion, especially inside arterioles and capillaries.

The viscocity of ketchup is much greater than the average 'liquid'. Just put it in the freezer and you can answer the question...

A fluid does not describe a state of matter. And since your options are either solid or liquid, fluid is not likely to be the answer.

Solids are able withstand an external force without deformation. Ketchup can't. Thus, it's a liquid.

But to be honest, your MCAT book is stupid for even asking. Who the fuck cares? This question is more of a technicality than anything important. It's a conversation starter, not a real science question. I suggest getting a different textbook, or studying something else, because that question is not likely to be on the actual MCAT.
