Absolute Zero Flashcards

All 5 cards in this deck

What is absolute zero?

−273 °C — the lowest possible temperature, at which the particles have no movement (no kinetic energy).

How do you convert a temperature from degrees Celsius to kelvin?

Add 273: temperature (K) = temperature (°C) + 273.

How do you convert a temperature from kelvin to degrees Celsius?

Subtract 273: temperature (°C) = temperature (K) − 273.

What is absolute zero on the kelvin scale?

0 K. The kelvin scale starts at absolute zero.

How does a temperature change of 1 °C compare with a temperature change of 1 K?

They are the same size — a rise of 1 °C is a rise of 1 K.
