Correct: Energy is REQUIRED for a phase change to occur, Solids have a definite shape and definite volume, Particles in a solid vibrate in place, Phases of matter are the same as states of matter, A liquid will take on the same shape as the container it fills  , The force of attraction between particles of a liquid are weaker than that of a solid, Plasma is the 4th phase of matter, which mostly exist in our universe, For freezing to occur energy must be removed, A phase change can sometimes "skip" an entire phase of matter. Example: A gas that changes directly into a solid, rather than a liquid first., When matter sublimates it "skips" the liquid phase, An example of deposition is snow or hail, Different substances have different freezing/melting points., The temperature in which a liquid becomes a gas is known as the boiling point., The freezing and melting points are always the same temperature, An example of sublimation is dry ice, Incorrect: The freezing point is the same as a substance's boiling point, In deposition a solid changes directly into a gas, skipping the liquid phase, When energy is added to matter, the space between the particles begin to decrease, A phase change in matter will only occur when energy is being added, An example of sublimation would be snow or hail, Whenever energy is removed a phase change can not occur, Condensation happens when energy is added to a liquid, Melting requires the removal of energy., The attraction between particles of a solid are extremely weak, Particles which make up a liquid are completely free to move aroundfreely,
