Question

What's absolute zero?

A. The temperature at which all liquids freeze
B. The temperature at which water freezes
C. The coldest temperature ever recorded in nature on Earth
D. The temperature at which all molecular motion is stopped

Answer 1

D
objects(with a temp of absolute zero)
molecular motion stop.
And it can’t be A because helium remains a liquid even past zero.
Even though water does freeze in absolute zero the best possible answer is D.

Answer 2

D. The temperature at which all molecular motion is stopped.

Step-by-step explanation:

Absolute zero is the theoretical temperature at which all matter would have zero thermal energy and all molecular motion would stop. This temperature is equal to -273.15 degrees Celsius or -459.67 degrees Fahrenheit. It is the lowest possible temperature in the universe and cannot be reached in practice, as it is impossible to completely eliminate all thermal energy from matter.
