Passage: "Dry ice," or solid carbon dioxide, is a substance that sublimes at atmospheric pressures. Dry ice is very cold (78C) and so is used as a coolant for goods such as ice cream that must remain frozen during shipment. Because the dry ice sublimes rather than melting, there is no liquid mess associated with its change of state as the dry ice warms. As you may have seen in demonstrations, dry ice merely transforms from a solid to a cold, steamy looking gas. Ferrocene (an iron-containing compound) is usually purified by sublimation by gentle warming at atmospheric pressure. In the Figure below , you can see the reddish ferrocene crystals deposited on the outside of that tube. Deposition is the change of state from a gas to a solid. Answer: dry ice

Ex Output:
What is the common term for solid carbon dioxide, which is used as a coolant?

Passage: The amplitude , , is the distance from the equilibrium (or center) point of motion to either its lowest or highest point ( end points ). The amplitude, therefore, is half of the total distance covered by the oscillating object. The amplitude can vary in harmonic motion but is constant in SHM. The amplitude of a wave often determines its strength or intensity; the exact meaning of "strength" depends on the type of wave. For example, a sound wave with a large amplitude is a loud sound and a light wave with a large amplitude is very bright. Answer: amplitude

Ex Output:
Often determining the strength or intensity of a wave, this term is the distance from the equilibrium point of motion to either its lowest or highest point?
