Question

what happens in the gray zone between solid and liquid?​

Answer 1

Answer:

Solids and liquids are well understood. ... A grain of sand is as solid as a rock, but a million grains can flow through a funnel almost like water. And highway traffic can behave in a similar way, flowing freely until it becomes blocked at some bottleneck.

Answer 2

Solids and liquids are well understood. But some materials act like both a liquid and a solid, making their behaviour hard to predict. Sand is one example.

A grain of sand is as solid as a rock, but a million grains can flow through a funnel almost like water. And highway traffic can behave in a similar way, flowing freely until it becomes blocked at some bottleneck.

So a better understanding of this “gray zone” might have important practical applications.

I hope its help for you☘️✨
