Phase changes are transitions between solid, liquid, and gas phases. For example, ice melting is an example of a phase change from a solid (ice) to a liquid (water). Phase changes involve changes in energy. Which of the statements regarding phase changes are true? Sublimation is the conversion of a gas to a solid. Freezing is the conversion of a gas to a liquid. Deposition is the conversion of a gas to a solid. Melting is the conversion of a...
