Question

turns frozen water into water vapors - skipping the melting stage
options: percolation, sublimation, evaporation, transpiration

Explanation:

We need to identify the process that turns frozen water (ice) directly into water vapor, skipping the liquid (melting) stage. Let's analyze each option:

• Percolation: Involves the movement of water through a porous medium (like soil), not a phase change of ice to vapor.
• Sublimation: By definition, is the phase transition of a substance from a solid directly to a gas, without passing through the liquid phase. This matches the description of turning frozen water (solid) into water vapor (gas) and skipping the melting (liquid) stage.
• Evaporation: Is the process of a liquid turning into a gas (e.g., liquid water to water vapor), so it starts from the liquid phase, not solid ice.
• Transpiration: Is the release of water vapor from plants (through leaves), involving liquid water in plants turning to vapor, not ice to vapor.

Answer:

Sublimation
