Question

Absolute zero is :

• A. the temperature at which all particles stop moving.
• B. at -273 kelvins.
• C. at 0 degrees Celsius.
• D. the temperature at which water freezes.
• E. the temperature at which all gases turn into liquids.

Answer 1

Answer: (A), (B)

The correct options are
A the temperature at which all particles stop moving.
B at -273 kelvins.

Absolute Zero is the $0K$, this is the temperature at which all particles stop moving.
Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to $-{273.15}^{o}C$ on the Celsius temperature scale
At this temperature the movement of the particles is considered to be zero.
