Hydrogen, for example (3) Crossword Clue
Answer: GAS (3 letters)
The answer to the crossword clue "Hydrogen, for example" with 3 letters is "GAS".Gas refers to a state of matter in which particles move freely, and hydrogen is an example of an element that naturally exists in this gaseous form. It is one of the most abundant gases in the universe and is commonly used in scientific, industrial, and energy applications.
Why "Gas" Fits
The clue asks for a single word (3 letters) meaning "Hydrogen, for example." The answer, GAS, fits perfectly:
- Hydrogen, for example: Gas is the scientific classification for hydrogen in its natural state, directly capturing the clue’s request for a general category of which hydrogen is an instance.
- Direct match: With three letters, gas fits the enumeration precisely.
- Precise meaning: The term encompasses all substances in the gaseous phase—oxygen, nitrogen, carbon dioxide, and others—meshing with hydrogen’s identity in chemistry and everyday life.
Gas is a fundamental concept in science, industry, and daily living:
Origin and usage:
- The word "gas" was coined in the 17th century by Flemish chemist Jan Baptist van Helmont, inspired by the Greek “chaos.”
- Used in physical science to describe one of the three classic states of matter, distinguished by loose molecular bonds and the ability to expand and fill any container.
Basic context:
- Hydrogen, along with oxygen and nitrogen, is an example of a chemical element at standard temperature and pressure that exists as a gas.
- Used in everyday speech for fuel gases (natural gas, cooking gas), atmospheric gases (air), and industrial gases.
Examples:
- “Hydrogen is the lightest gas in the periodic table.”
- “The explosion released toxic gases into the air.”
- “Filling a balloon with a gas like helium makes it float.”
In quick crosswords like “Hydrogen, for example (3),” clues about elements or scientific facts prefer the cleanest, most general group name:
Definition: “Hydrogen, for example” is a classic way of seeking a category name—gas rather than a specific attribute or function.
Clue type: Definition by example, leading directly to the general term.
Solving approach:
- For three-letter scientific category names, "gas" is the prototypical response; alternate answers like "air" or "oil" don't fit hydrogen’s state.
Crossword pattern: Basic physical science categories—gas, ion, acid, salt—are favorites for concise clues and universal classroom familiarity.
