Class 11 Chemistry Gases & Solutions States of Matter



Assertion :Smaller the droplets of water, spherical they are.
Reason :Force of surface tension is equal, and opposite to force of gravity.
(a)
Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
(b)
Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
(c)
Assertion is correct but Reason is incorrect
(d)
Both Assertion and Reason are incorrect
Correct answer: (b) 
Solution: It happens due to surface tension. Surface tension is that property of a liquid by virtue of which a drop of water behaves as a stretched elastic membrane and in that process, it tends to occupy minimum surface area and spheres have minimum surface area. Thus smaller droplets are spherical in shape. Surface tension is also a resultant of a adhesive force.
Both the statements are true.
Hence reason statement is not the correct explanation of Assertion.
