Solid or Liquid?

[joannekemeys]

Is toothpase a solid or a liquid and why?

[Obo]

surely Toothpaste is exactly what is says it is... a paste which is a mixture of both solid and liquid

[ravenhair]

I'd say a liquid - if you had a bucketful of it, you'd be able to pour it out.

Not being a chemist I can't be certain but the 2 states are not mutually exclusive. Aren't there others such as suspension, solution, emulsion etc? Many materials exist in different forms at different temperatures (ice, water, steam). Others can be dissolved in liquids eg sugar, salt. Some can be suspended (wood fibre in water to make paper) and then fitered back out again. As a comment, I don't think milk is technically a liquid. It may be a suspension or emulsion!! As for glass, tell me more Einstein.....!!!! If someone could give a proper definition of a liquid it would surely help.

I always thought what Einstein thought about glass flowing ... but then I read this post question 6451
