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 water? by what distance in meters? Then how do I calculate the volume and mass in kg of the water being moved up or down. Where do I begin? I know there is a formula how do I find it?
one more really stupid question
what effect does temperature have on surface tension?
