Solid: Molecules are tightly packed together into a fixed shape, so the molecules only have room to vibrate in place. ex: a classroom
Liquid: Molecules have room to spread out and can slide past each other and takes the shape of the container it's in. ex: a hallway
Gas: Molecules have room to go wherever and don't touch each other but still takes form of it's container. ex: outside; parking lot

Molecules have the highest amount of energy in the gas phase because the molecules are moving faster and have more kinetic energy compared to the solid and liquid phases.
Ptolemy did not explain Venus phases in his geocentric model because he believed that Venus, like all other planets, moved around the Earth in perfect circles and did not exhibit phases like the Moon. His model could not account for the varying phases of Venus because it was based on circular motion and did not include elliptical orbits or the correct understanding of planetary motion.
In the gas phase, molecules have the highest amount of energy as they possess greater kinetic energy and move more freely compared to the solid and liquid phases.
The phases that can be compressed are typically the gaseous and vaporous phases of matter. Liquids and solids generally cannot be compressed as easily due to their closely packed molecules.
