What is tension?

What does salt do to surface tension?
Why does water turn into a sphere?
Sorry for all the question but i need help, thanks in advance

Surface tension is a phenomenon in which the surface of a liquid, where the liquid is in contact with gas, acts like a thin elastic sheet. This term is typically used only when the liquid surface is in contact with gas (such as the air). If the surface is between two liquids (such as water and oil), it is called "interface tension."
Surface tension (denoted with the Greek variable gamma) is defined as the ratio of the surface force F to the length d along which the force acts:
gamma = F / d
Adding salt to freezing water lowers the temperature at which the
solution will freeze. In other words, adding salt to ice may make the
ice melt not because the salt raises the temperature but rather
because a new solution is formed that has a lower freezing point.
Salinity is the saltiness or dissolved salt content of a body of water. It is a general term used to describe the levels of different salts such as sodium chloride, magnesium and calcium sulfates, and bicarbonates. Salinity in Australian English and North American English may also refer to the salt content of soil.
Salt lowers the surface tension. This is because there are other charged ions in the water upsetting the waters hydrogen bonding which essentially gives it its surface tension.
A sphere is the geometrical shape that has the smallest surface area for its volume. The drop takes this shape because water molecules tend to stick to each other [because of there polar covalent bonds]. So, when not confined by a container, and with nothing around it to distort its shape, a very tiny water drop is perfectly round like a ball because the water molecules are pulling inward toward each other.

welcome. was it useful, Jennix??

all molecules of water stich to each other, but the molecules on top are stick to molecules under them, so there is tension in top surface of water called as ST.
