• A drop of water having a volume of 0.031416 cm³ is confined between two parallel glass plates ($\theta$ = 0°) space 0.01 cm apart. The drop is surrounded by air ($\sigma$ = 70 $\frac{dynes}{cm}$). How much below atmospheric pressure is the drop.

Step 1
First, let's calculate the surface area of the drop. The surface area can be calculated using the formula: Surface Area = 4πr² Given that the drop has a volume of 0.031416 cm³, we can find the radius (r) using the formula for the volume of a sphere: Volume = Show more…

. A water drop of radius 1mm is split into 106 identical drops. Surface tension of water is 72 dynes/cm. Find the energy spent in this process
Dharmendra M.
A drop of water of volume $V$ is pressed between two glass plates so as to spread to an area $A$. If $T$ is the surface tension, the normal force required to separate the glass plates (a) $\frac{T A^{2}}{V}$ (b) $\frac{2 T A^{2}}{V}$ (c) $\frac{4 T A^{2}}{V}$ (d) $\frac{T A^{2}}{2 V}$

A glass capillary of diameter 0.1 cm is dipped into water. Calculate the level of the water that rises in the capillary if surface tension of water = 72.75 dyne cm⁻¹ density = 0.9984 g cm⁻³ and contact angle for water = 10° (g = 980 cm sec⁻²).
