zero assoluto -273,15 °C

Absolute zero, because the lowest possible temperature is precisely –273.15 °C

The absolute zero it is the minimum temperature possible in principle: it corresponds to –273.15 degrees Celsius (°C) and represents the physical limit for cold, corresponding to the situation (unattainable in practice) in which the molecules, atoms or particles that make up a physical system are completely still and therefore have no vibrational motion. The concept was based on this ...
