Question

-Select ALL that apply-

Absolute zero is ___.

A. 0K
B. –40oC
C. –273oF
D. –273oC
E. the temperature at which water freezes
F. the temperature at which motion is at a minimum

Answer 1

The correct options are:
A) 0 K
F) the temperature at which motion is at a minimum

In fact, absolute zero corresponds to zero degrees in the Kelvin scale: 0 K. At this temperature, the motion of the molecules of any substance is minimum (it is zero, to be precise).

(note: there are some weird signs in the answers. if there is a negative sign in front of
`273^(\circ)C` in option D), then option D is correct as well, because
`0 K =-273^(\circ) C`).
