📖 1. Temperature Scales & Conversion

🔑 Key Concepts & Definitions

• Kelvin Scale (K): An absolute temperature scale where 0 K (zero Kelvin) represents the point at which particles are at their minimum thermal motion, corresponding to the "absolute zero."
• Celsius Scale (°C): A relative temperature scale where 0°C is the freezing point of water and 100°C is the boiling point at standard atmospheric pressure.
• Zero Absolute (0 K): The theoretical temperature at which all thermal motion ceases, equivalent to -273.15°C.
• Conversion Formulas:
  • $q (°C) = T (K) - 273.15$
  • $T (K) = q (°C) + 273.15$
• Temperature of a Body (T): A measure of the thermal energy content, which influences radiation emission and physical states.
