Which statement describes a characteristic of deposition?

• A. It is a chemical change where a gas reacts to form a liquid.
• B. It is a chemical change where a solid forms from a liquid.
• C. It is a physical change where a solid turns directly into a gas.
• D. It is a physical change where a gas transforms directly into a solid.

Answer: (D)

Verified step by step guidance

1. Understand the definition of deposition: Deposition is the phase change where a substance transitions directly from the gas phase to the solid phase without passing through the liquid phase.
2. Recognize that deposition is a physical change because it involves a change in the state of matter without altering the chemical composition of the substance.
3. Compare deposition with other phase changes: sublimation is the reverse process where a solid changes directly into a gas, and condensation is when a gas changes into a liquid.
4. Identify that the statement 'It is a physical change where a gas transforms directly into a solid' correctly describes deposition.
5. Note that the other options describe either chemical changes or incorrect phase transitions, so they do not accurately describe deposition.
