A scientist uses a hypsometer to measure the elevation of a mountain camp.

Definition

1. Noun:
   • An instrument for measuring altitude or height: A hypsometer is a scientific device that determines elevation above sea level by measuring the boiling point of water, which decreases with lower atmospheric pressure at higher altitudes.

Usage Examples

• Noun:
  • The surveyor used a hypsometer to determine the mountain's precise elevation.
  • A hypsometer is particularly useful in remote areas where traditional surveying equipment is unavailable.

Advanced Usage

• Scientific Context: In meteorology and geography, a hypsometer provides a method for altimetry based on thermodynamic principles, specifically the relationship between atmospheric pressure and the boiling point of a liquid.
  • The expedition's data relied on readings from a carefully calibrated hypsometer.

Variants and Related Words

• Hypsometric (adj): Relating to the measurement of heights or elevations.
  • The team created a hypsometric map of the region.
• Hypsometry (n): The branch of science concerned with measuring the heights of features on the Earth's surface.
  • His research focuses on the hypsometry of coastal plains.

Synonyms

• Altimeter: An instrument for measuring altitude.
• Boiling-point apparatus: A descriptive term for the device's function.

Notes on Meaning

• The term specifically refers to an instrument that uses the boiling point method. It is not a general term for any altimeter. Other types of altimeters, such as barometric or radar altimeters, use different principles.
