At 20 degrees celsius the surface tensions for water and mercury are 73dyn/cm and 470dyn/cm respectively. Find these values in SI units. A small capillary tube of 1mm diameter is placed into a container of 20 degree celsius water. will the level of the water in the tube move above or below the level of water? by what distance in meters? Next, calculate the volume and then the mass in kg. of the water being moved up or down. Repeat this problem for mercury.

What effect does temperature have upon surface tension? Is it better to wash clothes in hot water or cold water?
