Why Is Absolute Zero Unattainable? |
Absolute zero (0 K) is the lowest temperature that is theoretically possible. Absolute zero is so hard to reach because when something cools down, it loses to thermal energy. When it loses energy, it flows from hot to cold. For absolute zero to happen, a object must be surrounded by something that is colder than 0 K. Since there is not anything lower than absolute zero, absolute zero is not able to be reached.
