Lord Kelvin and the Absolute Temperature Scale

  1. William Thomson, known as Lord Kelvin, introduced the concept of absolute zero in the 19th century.
  2. Absolute zero is the theoretical temperature at which particles have minimal motion.
  3. Kelvin proposed a temperature scale starting at absolute zero, now called the Kelvin scale.
  4. The Kelvin scale eliminates negative temperatures, making it ideal for scientific calculations.
  5. Kelvin’s work linked thermodynamics with the laws of energy conservation.
  6. He refined the efficiency limits of heat engines and contributed to the second law of thermodynamics.
  7. The Kelvin scale is widely used in physics, chemistry, and astronomy.
  8. Absolute zero corresponds to −273.15°C or −459.67°F.
  9. Lord Kelvin’s ideas helped establish a rigorous framework for temperature and energy measurements.
  10. Today, the Kelvin scale is essential in studying cold phenomena, cryogenics, and the cosmos.
