QUESTION:
Problem 64PE
Calculate the contact angle θ for olive oil if capillary action raises it to a height of 7.07 cm in a glass tube with a radius of 0.100 mm. Is this value consistent with that for most organic liquids?
ANSWER:
Step 1 of 2:
A glass tube of a very small radius is inserted inside olive oil. The oil inside the tube rises vertically because of capillary action. We are going to calculate the contact angle between olive oil and the glass. It is the tangent to the liquid surface at the point where the solid and the liquid meet.
The height raised in glass tube or
The acceleration due to gravity
The density of olive oil
The surface tension of olive oil
The radius of the glass tube or
