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.
