• as permanent frost (called permafrost)
Water exists in ice form as permanent frost in the North and South Poles of Mars. The big slabs of ice are called polar icecaps.
• as liquid
So far, no liquid water has been found anywhere on Mars.
Not presently. There is no permanent liquid water, little atmosphere, and not protection from solar radiation.
It is too cold for liquid water to exist on the surface
could water exist as a liquid if we don't have a atmosphere
Not that we know of. The "air" pressure on Mars is so low that water cannot exist in the liquid state; it will be either a gas or a solid. We know that there is some water on Mars; at night, the water vapor condenses as frost onto solid surfaces, such as rocks or spacecraft.
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
The three states of matter in which water can exist are gas, liquid, and solid.
Three: solid, liquid, and gas (ice, liquid water, and fog or steam).
Water can exist in three phases which are solid, liquid, and gas. So liquid water is water in the liquid phase.
Water is a substance that can exist in all three states of matter: solid (ice), liquid (water), and gas (water vapor).
No. Venus is too hot for liquid water to exist.
