    The Physics of Thermometers, Temperature and Cold Atoms

    26 May 2026 | Prelims Only | Science and Technology
    Mains Paper 3: Awareness in various sc and tech fields

    Why in the News?

    An article in The Hindu explained the scientific principles behind thermometers, temperature scales, absolute zero, and ultra-cold atomic physics, highlighting how measurement of temperature evolved from mercury thermometers to quantum physics-based studies of cold atoms.

    What is Temperature?

    • Temperature is a measure of the average kinetic energy of atoms and molecules in a substance.
    • When heat is supplied:
      • Atoms and molecules move faster.
    • When heat is removed:
      • Their motion slows down.
    • Thus, temperature reflects the degree of atomic agitation inside matter.

    Celsius Scale

    • Developed by: Anders Celsius

    Basis of the Scale

    • 0°C: Freezing point of water
    • 100°C: Boiling point of water
    • The interval between these two points is divided into 100 equal parts.

    Mercury Thermometers

    Why Mercury is Used

    • Uniform expansion on heating
    • Easily visible liquid metal
    • Good thermal conductor

    Digital Thermometers

    • Modern digital thermometers use Semiconductor materials
    • Principle
      • Semiconductors conduct limited electricity.
      • Higher temperature releases more free electrons.
      • Increased electric current is measured electronically and converted into temperature readings.

    [2021] In a pressure cooker, the temperature at which the food is cooked depends mainly upon which of the following?
    1. Area of the hole in the lid
    2. Temperature of the flame
