The data show a clear negative relationship: as the temperature of the water increases, its surface tension decreases. The points lie along a steadily falling trend (approximately linear over the measured range).

Physical reason: higher temperature gives water molecules greater kinetic energy, which weakens the cohesive (intermolecular) forces at the liquid surface, so the surface tension drops. (At the critical temperature the surface tension goes to zero.)
