O Assignment Score: 40.9% Resources Hint Check Answer Question 22 of 22 > 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? Deposition is the conversion of a gas to a solid. Melting is the conversion of a solid to a liquid. Sublimation is the...
