Question

What r solid?explain the features of solids.

Answer 1

Answer:

Solid is one of the four fundamental states of matter. The atoms in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. 

A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas.

Answer 2

$\huge{\underline{\tt{Solids:-}}}$

In a solid, molecules are packed together, and it keeps its shape. Liquids take the shape of the container. Molecular motion for the particles in a solid is confined to very small vibrations of the atoms around their fixed positions; therefore, solids have a fixed shape that is difficult to change.
