Question
At which angle liquid will not wet solid.Zeroacute 45°obtuse
Solution
To determine at which angle liquid will not wet solid, we need to understand the concept of contact angle. The contact angle is the angle formed between the liquid-solid interface and the solid surface.
If the contact angle is less than 90 degrees, the liquid will wet the solid surface. This means that the liquid will spread out and adhere to the solid.
If the contact angle is greater than 90 degrees, the liquid will not wet the solid surface. This means that the liquid will form droplets and not spread out on the solid.
In the given options, "zero acute" refers to an angle of 0 degrees, "45 degrees" is an acute angle, and "obtuse" refers to an angle greater than 90 degrees.
Therefore, the angle at which the liquid will not wet the solid is an obtuse angle, which is greater than 90 degrees.
