Earth, of course, and possibly Mars. Recent photos of Mars show dewdrops of a liquid which certainly appears to be water condensing on the landing struts of the Polar Observer.
Yes.
Earth is the wettest known planet. It is the only planet known to have liquid water. The only other planet with any form of water is Mars with ice on one of the poles.
earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
We have never actually looked, but almost certainly there is no LIQUID water; there wouldn't be enough atmosphere to keep it liquid. There may be - probably is - water in the form of ice, but we won't know until we send a probe there.
They form when liquid water is vapored

Earth is located in just close enough from the sun where the heat from it keeps water melted mostly, and just far enough away where the water doesn't turn into water vapor.Liquid water is also capable of forming on Mars, if it had a stable, warm atmosphere.
Water exists in two forms Solid or Liquid. Water changes form when boiled, it becomes a vapor when boiled, that is 212 degrees Fahrenheit or 100 degrees Celsius. It changes from liquid to solid when it is subjected to temperature of 32 degrees Fahrenheit or 0 degrees Celsius. The chemical formula of water is 2 parts hydrogen and one part oxygen, and is the most abundant on our planet. Liquid hydrogen in a gaseous form is very volatile and unstable, but when combined with oxygen, it is very stable.
It is also found as a gas. This is because Earth orbits its star at a distance where the heat form the star is enough for water to be present in the liquid form. Extremes on the planet then allow for water to be solid and vapor in places.

So far, Earth is the only planet we know of that has all three states of water.The three states of water are: liquid, solid (ice) and gas (water vapor).
Mixing the two will yield sodium acetate and carbonic acid. In its pure form, devoid of water, acetic acid is very stable and very corrosive but in a water solution such as vinegar, it becomes less stable and breaks down releasing water in liquid form and carbon dioxide in a gaseous form.
I presume when you say "form" you mean state, and if I presume correctly the answer is all three states: gas, liquid and solid. However, liquid is the most predominate state.
We have never actually looked, but almost certainly there is no LIQUID water; there wouldn't be enough atmosphere to keep it liquid. There may be - probably is - water in the form of ice, but we won't know until we send a probe there.
Water molecules are already in liquid form.
