Finding the Opposite of Condensation
The question asks us to find the word or group of words that is opposite in meaning to the underlined word "condensation" in the given sentence: "The first step in precipitation is condensation."
Let's first understand the word "condensation" in the context of precipitation, which is part of the water cycle. Condensation is the process where water vapor (a gas) in the air changes into liquid water. This is how clouds form. For precipitation (rain, snow, etc.) to occur, moisture in the atmosphere must condense.
We need to find the opposite of this process.
Analyzing the Options
Let's look at the given options:
- constriction: This means making something narrower or tighter. This is not related to the change of state of water.
- abridgement: This means shortening or reducing something, like a text or piece of writing. This is not related to the change of state of water.
- recapitulation: This means summarizing or restating the main points of something. This is not related to the change of state of water.
- evaporation: This is the process where liquid water changes into water vapor (a gas). This is the opposite process of condensation, where water vapor changes into liquid water. Evaporation happens when water heats up and turns into a gas, rising into the atmosphere. Condensation happens when water vapor cools down and turns back into liquid water.
Comparing the options, evaporation is the direct opposite process to condensation in the context of the water cycle and changes of state of water.
| Word | Meaning/Context | Relation to Condensation |
|---|---|---|
| Condensation | Water vapor (gas) changes to liquid water. Essential step before precipitation. | The base word to find the opposite of. |
| Constriction | Making something narrower or tighter. | Not an opposite. |
| Abridgement | Shortening or reducing. | Not an opposite. |
| Recapitulation | Summarizing or restating. | Not an opposite. |
| Evaporation | Liquid water changes to water vapor (gas). | The opposite process. |
Conclusion
The process opposite to condensation (gas to liquid) is evaporation (liquid to gas). Therefore, the correct opposite of "condensation" is "evaporation".

| Evaporation | The process by which liquid water changes into a gas or vapor. |
| Constriction | The action of making something narrower. |
| Abridgement | A shortened version of a larger work. |
| Recapitulation | An act or instance of summarizing and restating the main points of something. |
Additional Information: The Water Cycle Stages
Condensation is a crucial part of the water cycle. The main stages of the water cycle include:
- Evaporation: Liquid water from oceans, lakes, rivers, and soil turns into water vapor due to heat from the sun.
- Transpiration: Water is released into the atmosphere as vapor from plants.
- Condensation: Water vapor in the atmosphere cools and changes back into tiny liquid water droplets or ice crystals, forming clouds.
- Precipitation: When the water droplets or ice crystals in clouds become too heavy, they fall back to the Earth's surface as rain, snow, sleet, or hail.
- Collection/Runoff: Precipitation is collected in bodies of water (lakes, oceans) or flows over the ground (runoff) to eventually return to rivers, lakes, or oceans, or it infiltrates into the ground.
Condensation and evaporation are opposing processes in terms of the change of state of water.
