Thân thiện

A scientist uses a tensiometer to measure the surface tension of a water droplet.

Definition

1. Noun:
   • A measuring instrument for measuring the surface tension of a liquid: A device used in physics and chemistry to determine the force per unit length at the surface of a liquid.
   • A measuring instrument for measuring the tension in a wire or fiber or beam: A tool used in engineering and materials science to gauge the pulling force within a solid object.
   • A measuring instrument for measuring the moisture content of soil: A device used in agriculture and environmental science to assess the water tension or potential in soil, indicating how hard plants must work to extract water.

Examples of Usage

• Noun:
  • The scientist used a tensiometer to measure the surface tension of the new solvent.
  • Before installing the cable, engineers checked its tension with a tensiometer.
  • Farmers rely on a tensiometer to determine when to irrigate their crops.

Advanced Usage

• Scientific Context: In laboratory settings, a tensiometer is crucial for experiments involving capillary action, wetting phenomena, or material strength.

  • The research paper detailed the use of a high-precision tensiometer for the study.

• Agricultural Application: Soil tensiometers are often installed at root depth to provide continuous data on soil water status.

  • The automated irrigation system is triggered by readings from the buried tensiometers.

Variants and Related Words

• Tensiometry (n): The science or process of measuring tension or surface tension.
  • Tensiometry is a fundamental technique in colloid science.

Synonyms

• Surface tension meter (for the first definition).
• Tension gauge or force gauge (for the second definition).
• Soil moisture sensor or soil water potential meter (for the third definition, though these may use different principles).

Related Phrases

• Tensiometer reading: The numerical value obtained from the instrument.
  • A low tensiometer reading indicates the soil is wet and water is easily available to plants.
