Air is a fluid.
What... how?
Difference between the colloquial and technical definitions of fluids. Colloquially, fluids are liquids. But technically, for example when discussing physics, it's any substance of no fixed shape.
I was about to argue with you but the dictionary says you are right.
Take my upvote.
In english generally we see liquids to be the same as fluids but technically liquids are a state and fluids are matter that flows. Similarly we will see accuracy and precision as the same thing but accuracy is within a range where precision is exact.
As an example: Strawberries and raspberries aren't even berries but pumpkins are botanically speaking. I would be accurate to regard strawberries and raspberries as berries as we use them as berries but I would not be precise.
According to any hydrodynamics code, so are solids.
