👉 Any substance which can flow with relative ease, tends to assume the shape of its container, and obeys Bernoulli's principle; a liquid, gas or plasma.
Alright class, settle down, let’s take a peek,
At the word “fluid,” something we need to speak!
The dictionary gives us a helpful clue,
“Any substance that flows, it’s true!”
Now, think of water in a glass so bright,
It takes the shape – a lovely sight!
That's because it’s
fluid
, flowing free,
Moving with ease for all to see.
Let’s break it down, let’s make it clear,
A fluid can be liquid, gas, or plasma here!
Liquids
like juice and oil, they pour,
Taking the shape of what's in store.
Gases
like air – so light and fast,
They spread out freely, built to last.
Plasma
, well, that’s a fiery state,
Like stars and lightning, don’t hesitate!
And Bernoulli’s principle? That's a bit more deep,
It talks about speed and pressure, secrets they keep. A fluid moving fast will have less pressure, you see, it’s a fascinating decree!
So, "fluid" means something can flow with grace,
Taking the shape of its space!
