Two scales, one absolute zero

The thermodynamic (Kelvin) scale does not depend on any particular substance. Its zero, absolute zero, is the temperature at which particles have least kinetic energy. The Celsius scale is simply shifted: T in kelvin equals the Celsius value plus 273.15. Slide the temperature and watch the particles slow as you approach 0 K.

Mission Predict the thermodynamic temperature in kelvin that matches 27 °C. Streak 0Best 0
A temperature of 27 °C is, on the thermodynamic scale:
Celsius temperature27 °C
thermodynamic temperature T = θ + 273.15300 K
Absolute zero is 0 K = −273.15 °C. A change of one kelvin equals a change of one degree Celsius, so only the zero point differs.
