are free to move in a container but are in close contact with one another
|
Detailed explanation-1: -This describes the liquid state. In a liquid, the particles are still in close contact, so liquids have a definite volume. However, because the particles can move about each other rather freely, a liquid has no definite shape and takes a shape dictated by its container.
Detailed explanation-2: -In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles.
Detailed explanation-3: -From the descriptions, the state of matter where particles are close together but are free to move around each other is a liquid.
Detailed explanation-4: -The particles in a liquid are separated by spaces that are large enough to allow the particles to slide past each other.
Detailed explanation-5: -In solids, the particles are tightly packed together. In liquids, the particles have more movement, while in gases, they are spread out.
