QJEEM24Ph0db2: JEE Main 2024 Physics - Class 11 JEEM24Ph0db2 Solution: Given below are two statements: Statement I : If a capillary…

Given below are two statements:

Statement I : If a capillary tube is immersed first in cold water and then in hot water, the height of capillary rise will be smaller in hot water.

Statement II : If a capillary tube is immersed first in cold water and then in hot water, the height of capillary rise will be smaller in cold water.

In the light of the above statements, choose the most appropriate from the options given below

Multiple Choice Options

  • A Both Statement I and Statement II are false
  • B Both Statement I and Statement II are true
  • C Statement I is true but Statement II is false
  • D Statement I is false but Statement II is true

Step-by-Step Verified Solution

Surface tension will be less as temperature increases

h=2 Tcos⁡θρgr\mathrm{h}=\frac{2 \mathrm{~T} \cos \theta}{\rho \mathrm{gr}}

Height of capillary rise will be smaller in hot water and larger in cold water.
