Question

state any two characteristic of angle of contact for a liquid in constant with a solid​

Answer 1

Answer:When the liquid is in contact with solid, the angle between the solid surface and the tangent to the free surface of the liquid at the point of contact,measured from inside the liquid is called the angle of contact.

Two characteristic of angle of contact for a liquid in constant with a solid​

1 The angle of contact is constant for a given liquid-solid pair

2 If The angle of contact is large the surface is not wetted. Mercury does not wets glass.

Answer 2

When a liquid comes in contact with a solid, then the angle formed between the solid surface and the free surface of the liquid at the point of contact, is called the angle of contact.

Explanation:

Angle of contact is defined as:

When a liquid comes in contact with a solid, then the angle formed between the solid surface and the free surface of the liquid at the point of contact, is called the angle of contact.

• It has two characteristics:
• Angle of contact for a liquid in constant with a solid​
• The angle of contact is constant for a given liquid-solid pair
• If The angle of contact is large if the surface is not wet.
