Air is a fluid.
I was about to argue with you but the dictionary says you are right.
Take my upvote.
The first time I read this, I thought you were saying that strawberries and raspberries are pumpkins. I was very confused.
Names not fitting botanical definitions are due to the names being given before we (people) knew what we were talking about. DNA kind of came and shook things up, well even before that but what ever.
Also pineapples are neither apples nor grow on pine trees. And in many European languages the word for orange mean apple from China. Example appelsin, where sin in this case comes frome Sina or China
It depends on context, and I think most people realize this intuitively. If you put pumpkin in somebody's berry smoothie they're going to be pissed no matter what the scientific community says lol. It's the kind of thing that only matters for trivia.
And honestly science appropriated the term from common parlance, not the other way around. So a layperson could just as easily walk into a botany lab and say "fun fact, these actually are berries" and be completely correct.
What... how?
fluid includes both liquids and gasses.
It flows
what about a glacier? it's solid but it kinda flows too
So does glass almost, glass is not a liquid, there are more than 5 stated of matter, a lot more, but glass is still a type of solid. It has some characteristics that recemble the characteristics of a really slow moving liquid.
Well glaciers contain both solid and liquid parts. When you compress ice it turns to liquid. Water isn't really easy to compress, liquid water can be lower than 0c (freezing), which is called super cooled, and it turns to ice when it'd not compressed anymore. You can make super cooled water or even soda at home, and if you give the bottle a shake it will turn to ice in a couple of seconds. Also the ground under the glacier will be moved together with the ice and water, there is do much force there. When a part of a glacier breaks off it's called calving, like when a cow gives birth to a calf
According to any hydrodynamics code, so are solids.
