Question

1. Arrange the following in increasing order of surface tension
(1) water
(11) ethanol (111) hexane
(A) I < Il < 1/1
(B) II < < III
10) III < I< 11
(D) III < II < 1​

Answer 1

Explanation:

water surface tension 72

cyclohexane surface tension 24

Ethanol surface tension 22.10

order 1

$1 > 3 > 2$
