Statement I: All molecular motion ceases at $- 273^{0} C$
Statement II: Temperature $- 273^{0} C$ cannot be attained.

Moderate

A

If both statement I and statement II are true and statement II is the correct explanation of statement I.
B

If both statement I and statement II are true but statement II is not the correct explanation of statement I.
C

If statement I is true but statement II is false
D

If both statement I and statement II are false

Solution

When T = $- 273^{0} C$ = -273 + 273 = 0 K
Hence, c = 0 as c = $\sqrt{T}$
All molecular motion stops. According to Charles'law, the lowest attainable temperature is $- 273 . 15^{0} C$
