Question

which of the following is/are the characteristic(s) of solids?
a a definite shape
b a definite volume
c incompressibility
d all of the above

Explanation:

Solids have a definite shape because their particles are closely packed and held in fixed positions, so they don't take the shape of their container. They have a definite volume as the particles are in a fixed arrangement with a set amount of space they occupy. Solids are incompressible because the particles are already very close together, and there's little space between them to be compressed further. So all the options (a, b, c) are characteristics of solids.

Answer:

d. All of the above
