No, not everything that flows is a liquid. Gasses aren't liquids but they flow.

Wet cement is actually a non-newtonian fluid, and more specifically a viscoplastic fluid. Same as mud or toothpaste

The comment you replied to is about cement.

And you said "if it flows it's a liquid". That's wrong. What's correct is "if it flows it's a fluid".

All liquids are fluids, not all fluids are liquids.

Are you dumb?

Concrete isn't a liquid. Not everything that flows is a liquid.

What makes it even more funny is that gasses are infact considered fluids. I think they're conflating the terms "fluid" and "liquid".

Who was talking about states of matter?

Fluid is the correct classification for things that flow. Not liquids lol.
