The most critical factor that allows liquid water to exist is the average temperature of the planet. This is primarily dependent on the temperature of the star it orbits, and its distance from the star. Other lesser but important factors include atmospheric composition and pressure, rate of rotation, and inclination to the orbital plane.
If our solar system is typical, there is a huge amount of water in space, but it is mostly frozen solid on far planets, asteroids, and comets (and in the rings of Saturn). The liquid phase requires a temperature that is warmer, but not too warm. Astronomers refer to the potentially human-habitable region around any given star as the "Goldilocks zone" or Liquid Water Belt.
In our Solar System only Earth. Venus and Mercury are too hot and the outer planets too cold for liquid water.
The interparticle distance is greater in a gas than in a liquid, and greater in a liquid than in a solid.
terrestrial means a planet that is solid and not a gas giant, however even the solid planets have liquid interiors.
Earth is just the right distance from the sun, receiving just enough energy to allow liquid water to exist on the planets surface. If earth were a little further away, then the water would be frozen as ice, while much closer and the water would boil away as water vapour. Liquid water is essential for allowing life to exist.
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
The earth is in what astronomers call the 'Goldylocks Zone': Just the right distance from our sun that liquid water can exist.
In our Solar System only Earth. Venus and Mercury are too hot and the outer planets too cold for liquid water.
Yes it does
Earth is the only known planet with liquid water.

Gas and Liquid Gas.
The interparticle distance is greater in a gas than in a liquid, and greater in a liquid than in a solid.
Because on most planets (mars being an exeption as there are places where water can stay liquid) temperature and/or atmospheric pressure is to high or low for water to stay liquid.
The distance of the earth from the sun is enough to heat and cool the water in the earth. And the distance makes it possible for life to survive because it is the only distance where water is liquid. Try looking at the other planets in our solar system. Some has water in gaseous state. And some has it in solid state. Earth is the only planet in our solar system to have water in liquid state.
