Temperature-Kelvin

1.Who was Kelvin named after? Terence William Thomson 1st Baron Kelvin. 2.How does the Kelvin scale relate to Celsius/Fahrenheit? Fengjie 0K = 0-273.15°C = -273.15°C (same magnitude) 0K = 0x9/5-459.67°F = -459.67°F (different magnitude) Source: []

3. Why does kelvin start at the hypothesised abosolute zero? ~Matthew (a)This is because in experiments dealing with negative temperatures, the use of the kelvin allows less room for misunderstanding and makes calculations involving temperature simpler due to it being proportional with kinetic energy of particles. (Own understanding)

(b)Absolute temperature scales have the advantage that the temperature on such a scale is directly proportional to the actual average molecular translational energy, the property that is measured by temperature. For example, if one object has twice the Kelvin temperature of another object, the molecules, or atoms, of the first object actually have twice the average molecular translational energy of the second. This is not true for the Celsius or Fahrenheit scales, because their zeroes do not represent zero energy. For this reason, the Kelvin scale is the only one that is used in scientific calculations.
