How do molecules move?

gas vibrate and move freely at high speeds. liquid vibrate, move about, and slide past each other. solid vibrate (jiggle) but generally do not move from place to place.Click to see full answer. Also question is, why do molecules move?Kinetic theory of matter: All matter is made up of atoms and molecules that are constantly moving. When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. They contract when they lose their heat. do all molecules move? All molecules are in constant motion. Molecules of a liquid have more freedom of movement than those in a solid. Molecules in a gas have the greatest degree of motion. The green lines represent hydrogen bonds between water molecules. In this regard, how does molecules move in a solid? The atoms in a solid are so attracted to each other that they vibrate and don’t move past each other. The molecules of a liquid are attracted to each other, but move more freely and past one another.Why do gas molecules move rapidly?Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.
