Detailed explanation-1: -Gas In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.
Detailed explanation-2: -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.
Detailed explanation-3: -Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. A gas will fill any container, but if the container is not sealed, the gas will escape.
Detailed explanation-4: -Molecules vibrate as if all the bonds between the atoms are little springs. The vibrational motion of a given molecule can be expressed as a linear superposition of many vibrational patterns in which all the atoms oscillate at the same frequency.
