Thanks for stopping by, this is 2 Minute Classroom and today we are talking about viscosity.

I’ll first give a general definition of viscosity and then we’ll look at some examples to make sure it’s crystal clear.

Viscosity refers to a substance resistance to flow. In essence, how fluid it is. A substance with a low viscosity will have very little resistance to flow, meaning it flows easily and quickly; while a substance with high viscosity will strongly resist flow, meaning it flows very slowly.

Let’s look at some examples.

Water has a low viscosity, it flows easily. Spills out of a glass, splashes in a pool, and runs down your face when you cry.

Other examples of low viscosity fluids include oil, milk, and blood.

Honey has a high viscosity because it has a high resistance to flow. You have to squeeze the container to get it out, it globs up and has to be spread around with a knife, it does not easily flow.

Other examples of high viscosity fluids include molasses, glue, and even peanut butter (which has such a high viscosity it acts like a solid).

It’s also important to note that viscosity varies with temperature. Heating up honey in the microwave increases its viscosity.

Thanks for watching and I’ll catch you next time.

I thought topics like viscosity was really confusing until u made me understand it clearly and
Thank u very verrry Congrats to you plus 10 stars ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

I live for these reviews.
I don't want to forget these things over time just because I haven't been to school for a while. Thanks! 💕

This was very understandable, thank you! ☆

[vkss]

I want you to appreciate you in my mother tongue

Thala nee vere level uhh

[theresasmith]

Ty for this information i never understand that with resin now i do

[JayRazah]

Does high viscosity mean more blood volume in the body ?

[stamb]

bro, i just stopped by, and I have to say that ur awesome! (no hate but if u can, I think everyone would enjoy u getting a better mic)

It would have been nice to learn more about the word "viscosity" to fully understand the foundation of the number and its scope.
