WHAT’S SO SPECIAL ABOUT WATER: SURFACE TENSION

WebSurface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water … WebAnswer. about 65°C. The vapor pressure curve for water is not exactly zero at the melting point 0°C. Even ice has a vapor pressure; that is why it sublimes over time. However, the vapor pressures of solids are typically much lower than that of liquids. At −1°C, the vapor pressure of ice is 4.2 torr. simply be offers

"WebFIGURE 2. Next, explain the role of surfactants to students. A surfactant is a substance that reduces the surface tension of a liquid. For instance, a small puddle of water on a desk has high surface tension. But adding a surfactant such as dish soap to the puddle would reduce its surface tension and cause the water to spread out more. " - How does surface tension occur in water
