Surface tension is measured by devices such as the one shown in the Figure attached. In this particular case, a small circular wire loop attached with thin wires is brought down to the surface of the liquid and then pulled in the opposite direction Then, surface tension is measured using the length of the wire and the force that is required to pull the wire up. Calculate the force to break the surface tension on the wire from water if the surface tension at 20°C is 7.28 x 10-2 N/m and 6.96 x 10-2 N/m at 40°C.
