What are the properties of the liquid surface?

Best answer: Surface tension: The surface of a liquid has a macroscopic tension that makes the liquid surface shrink to the minimum as much as possible, which is called surface tension. Additional pressure on curved liquid surface: the pressure difference between inside and outside the curved liquid surface is called additional pressure. Gross suction phenomenon: the liquid level of wet pipe wall rises in thin pipe, while the liquid level of non-wet pipe wall falls in thin pipe.

Liquid is one of the three major material forms. It has no definite shape and is often influenced by the container. What is the shape of the container, the liquid will take on what shape when it is injected. However, its volume is constant in an environment with constant pressure and temperature. In addition, the liquid exerts pressure on the edge of the container just like other states. This pressure is transmitted in all directions, which not only does not decrease but also increases with the depth (which is why the deeper the water is, the higher the water pressure is).

Heating or depressurizing can generally vaporize a liquid into a gas, for example, heating water into steam. Pressurization or cooling can generally solidify the liquid into a solid, for example, cooling water into ice. However, pressurization alone cannot liquefy all gases, such as oxygen, hydrogen, helium, etc.
