Question

On the basis of the Kinetic Theory of Matter explain why?
a - solids have fixed shape and a fixed volume
b - liquid have a fixed volume but not fixed shape
c - gases have neither a fixed volume not fixed shape​

Answer 1

Answer:

Solids have a fixed shape and a fixed size. The particles are very close together and held in place by strong forces (bonds). Their particles cannot move around, but they do vibrate. Because the particles cannot move around, a solid has a fixed shape.

Liquid conforms to the shape of its container but has a fixed volume; it contains relatively densely packed molecules.

Gaseous fills its container completely—regardless of the container’s size or shape—and consists of widely separated molecules.
