👉 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, letās take a peek, At the word āfluid,ā something we need to speak! The dictionary gives us a helpful clue, āAny substance that flows, itās true!ā Now, think of water in a glass so bright, It takes the shape ā a lovely sight! That's because itās fluid , flowing free, Moving with ease for all to see. Letās break it down, letās 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 ā so light and fast, They spread out freely, built to last. Plasma , well, thatās a fiery state, Like stars and lightning, donāt hesitate! And Bernoulliās 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, itās a fascinating decree! So, "fluid" means something can flow with grace, Taking the shape of its space! Do you understand? Any questions to share?
