earth is the only planet where the same substance can exist in gaseous , liquid , and solid form
It has a large quantity of liquid water.
liquid & vapor
because the they need Very HIGH TEMPERATURE TO CHANGE STATE...and we cannot supply that very high temperature
a molecule can be a compound if it is made of more than one type of atom.
Nope. Mercury is normally a liquid. Many acids and other compounds are routinely liquid. Blood can be 'pure.'
water is the substance
... the substance can exist in the solid, liquid, and gaseous phases all at the same time.
Any chemical difference exist.
Yes
Francium can be solid, liquid or gaseous.
Solid, liquid, gaseous and plasma.
Yes. In fact, there is a specific combination of pressure and temperature where the solid, liquid, and gaseous phases can co-exist. Do some reading on "triple point".Yes.

Water
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.
Substance at Vapour - Liquid phase equilibrium can exist as both liquid or gas at the same time.
Solid, liquid, gas, or plasma. A substance can occur in any one these states. All matter occurs in one of these 4 states. These are the 4 states of matter.
In a state (solid, liquid, gas)
