Question

Explain shape of liquid drop
on solid Surface​

Answer 1

Answer:

Figure 4.10. Contact angle and interfacial tensions. When a drop of liquid on a solid surface does not spread, the drop will assume a shape that appears constant and exhibits an angle φ, called contact angle. Contact angle describes the shape of a liquid drop resting on a solid surface. ... Diagram of contact angle tester.

Answer 2

Answer:

hlo✔

Shape of liquid drop based on surface tension - definition

T1= Force due to surface tension at the liquid-solid interface. T2= Force due to surface tension at the air-solid interface. T3= Force due to surface tension at the air-liquid interface. For the equilibrium of the drop, T2=T1+T3cosθ..
