So this question popped up randomly to me for no reason: water seems to stick to clothing, but I was wondering why this is, since to me it seems it should just fall right off the clothes meaning you'd never have to dry them :wink:
I suppose mabye it has to do with surface tension, mabye the...
can anyone help me out with this question:In order to lift a wire ring of radius 2.07 cm from the surface of a container of blood plasma, a vertical force of 1.90×10-2 N greater than the weight of the ring is required. Calculate the surface tension of blood plasma from this information.
I can't...
By definition, surface tesnsion is the force at the surface of separation of two fluids and it's unit is N/m. my doubts are
1. Is it the force per unit length?
2. Does Surface tenson changes with change in lenth of the liquid container?
At 20 C degrees the surface tension for water is 73 dyn/cm and mercury is 470 dyn/cm how do I find this value in SI units?
part 2
a small capillary tube of 1mm diameter is placed into a container of 20 degree C will the level of the water in the tube move above or below the level of the...
