EVERYDAY SCIENCE

Detailed explanation-1: -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.

Detailed explanation-2: -Complete answer:-In solids the molecules move slowly because the space between the molecules is very less and they are tightly packed in a rigid structure.

Detailed explanation-3: -In a solid, atoms are packed tightly together and move very slowly. In fact, they do not flow at all: they simply vibrate back and forth. Because the atoms in a solid are so tightly packed, solid matter holds its shape and cannot be easily compressed. Solids also have a definite volume.

Detailed explanation-4: -Answer and Explanation: The solid state of matter has the slowest moving particles. Solids have defined shapes, and the spaces between atoms are very less as atoms are closely packed. Therefore, the movement of particles in solids is very less.

Detailed explanation-5: -Matter in the liquid state maintains a fixed volume (assuming no change in temperature or air pressure), but has a variable shape that adapts to fit its container. Its particles are still close together but move freely.
