Which state of matter is characterized by particles being tightly packed with limited movement?

The state of matter characterized by particles being tightly packed with limited movement is the solid state. In solids, the particles are arranged in a fixed, closely packed structure, which allows them to maintain a definite shape and volume. The limited movement of particles in solids is typically restricted to vibrational motion around their fixed positions, which is why solids do not flow or take the shape of their container as liquids and gases do. This unique arrangement provides solids with their rigidity and structural integrity.

In contrast, liquids have particles that are close together but can slide past one another, allowing them to flow and take the shape of their container. Gases consist of widely spaced particles that move freely and rapidly, resulting in the ability to fill the entire volume of their container. Plasma, another state of matter, consists of ionized particles with very high energy and is commonly found in stars, including the sun. This differentiation in particle arrangement and movement is crucial in understanding the properties and behaviors of the various states of matter.
