Assertion :A capillary is dipped in a liquid and liquid rises to a height $h$ in it. As temperature of the liquid is raised, the height $h$ increase (if the density of the liquid and angle of contact remain the same) Reason: Surface tension of a liquid decreases with the rise in its temperature.

Solution

The correct option is C Assertion is incorrect but Reason is correct
Assertion is incorrect but the reaton is correct.
We know that,
$h = \frac{2 T cos θ}{R 1 g}$
As the temperature is raised, the surface tension $(T)$ decreases.
As a result, the capillary raise $(h)$ also decreases if density $(e)$ and contact angle $(θ)$ in unaltered.

can be derived from Van der Waal's equation.

Q. Assertion : In the bonding molecular orbital (MO) of

H_{2}

, the electron density is increased between the nuclei.
Reason : The bonding MO is

ψ_{A} + ψ_{B}

, which shows destructive interference of the combining electron waves.
