Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.

In any experiment there are two groups set up. One is called the control group (sample with normal characteristics) and the other is the experimental group. Control group is also sometimes called placebo.

Water forms hydrogen bonds, which gives it a strong surface tension.

In the SI system the derived unit is the cubic metre. Divisions of this are litres and millilitres etc.

Other systems use other units. They include any cubic measurement and such specialised units such as gallons, pints, cups, etc.

You can cube any unit of length: cubic meter, cubic millimeter, cubic decimeter , cubic light-year, cubic inch, cubic foot. There are also non-standard (non-SI) units for volume that are not directly derived from a length, for example in the imperial system, the gallon, the bushel, etc. One weird thing about these units is that different units are used to measure liquids than to measure grains, for example.

Also, apparently identical units (the gallon, for example) are different on either side of the Atlantic!

See the link below for around 100 units of volume. There are many more!

That depends entirely on the system you're asking about. I'll just compare the primary English units to the SI units.

English:

Fl oz (fluid ounce)

Cup (8 fl oz)

Pint (2 cups, 16 fl oz)

Quart (2 pints, 4 cups, 32 fl oz)

Pottle, or half gallon (2 quarts, 4 pints, 8 cups, 64 fl oz)

Gallon (2 pottles, 4 quarts, 8 pints, 16 cups, 128 fl oz)

There are some other units of measurement within the English system, but they are almost never used in everyday life.
