"surface tension"
Surface tension causes molecules to hold to themselves more tightly. Therefore high surface tension liquids, like pure water, will form a taller drop and low surface tension substances, like oil, will spread out and be flat.
No. Vodka doesn't freeze ;)
Certain: An object heavier than water usually sinks to the bottom. If you gently place it on the surface however, it might float on the surface due to surface tension. This can obviously not be attained with something like a brick. You need something small like a needle to get to see this effect. Not certain: My guess is that this has something to do with hydrogen bridge bonds. (Something similar to a chemical bond but far weaker.)
Water is the only substance that expands as it cools. As water cools from 40C to 00C (the freezing point of water), water becomes a solid, and expands in its volume. The freezing point of alcohol is lower than water, so by simple observation, no change will appear. If you had accurate enough measuring equipment, you would see that the alcohol is taking up less volume.
Surface tension. It is caused by cohesion, or that molecules tend to feel attracted to like molecules.

Surface Tension-Surface tension is a property of the surface of a liquid that allows it to resist an external force. It is revealed, for example, in floating of some objects on the surface of water, even though they are denser than water, and in the ability of some insects (e.g.Water striders) and even reptiles (basilisk) to run on the water surface. This property is caused by cohesion of like molecules, and is responsible for many of the behaviors of liquids.
Surface tension causes molecules to hold to themselves more tightly. Therefore high surface tension liquids, like pure water, will form a taller drop and low surface tension substances, like oil, will spread out and be flat.
The meniscus is the curve at a liquid's surface by which one measures the volume of the liquid. A meniscus can be concave or convex depending on whether it is attracted to itself or the glass.
the surface tension of water is responsible for spherical shape of a drop.
No. Surface tension is a characteristic of liquids, not solids like a juice box.
The property of flowing very slowly in liquid is called viscosity. A liquid with high viscosity flows very slowly, like syrup or tar. A liquid with low viscosity flows quickly, like water.
Not all liquids are flammable. Some liquids that are flammable are gasoline, alcohol, oil. Liquids like water are not flammable.
That depends. Some liquids (like water and alcohol, or water and vinegar) mix, some (like water and oil) don't.
Only the few liquids that expand when they freeze like water. But yes, they can.
it's called "surface tension". It is the property of the surface of a liquid which causes it to behave like an elastic sheet. This is why a "water strider" insect can skate across the surface of a pond without sinking into the water. It is also what causes a drop of water - the surface tension of the water pulls it into a ball.
