Question

At which temperature does the motion of atoms and molecules stop
(A) 0 degrease C
(B) 0 C
(C) 0 degrease K
(D) 0 K

Answer 1

0K. This is absolute zero.

Answer 2

Answer:

(D) 0 K

Explanation:

Zero Kelvin, also known as the absolute zero is the temperature at which the atoms' motion will stop. This is the lowest temperature possible.

When atoms or molecules are heated they start moving. The magnitude of motion depends on the heat given to them. At absolute zero this motion will stop completely.

Zero Kelvin = -273.15 °C = 460 °F

Here it should be noted that while writing temperature in Kelvin scale it is not denoted with degree (°).
