The icy surface of Europa appears to be broken up into segments not unlike the tectonic plates on Earth. The surface appears, in geologic terms, to be rather young. If the surface is moving as we have found, then there is most likely a liquid layer under the ice.
If enough energy is absorbed by liquid water, it will eventually reach its boiling point and start evaporating into steam. This process is known as boiling and the water will undergo a phase change from liquid to gas.
It is by condensation that water vapor changes to liquid water.
When water changes from a liquid to a gas, it is evaporating or boiling. The "heat and energy" of the water molecules increases in the gaseous state. In fact, water molecules must pick up energy to change state from a liquid to a gas. Water molecules that are free to move as a gas have more kinetic energy than water molecules in a liquid form (as long as the liquid is not pressurized). The "heat and energy" of the H2O molecules that are now a gas is higher than that of liquid water.It should be noted that the thermal energy (heat) necessary to cause water to change state and become a liquid must come from somewhere. In evaporation, the energy necessary for the water molecule to escape from the liquid comes from the liquid. The liquid cools. We know that if we wet our finger and blow on it, it feels cool because evaporating water cools liquid water from which it escapes. That evaporating water has taken energy from the liquid water.In the case of boiling, water molecules take energy from liquid water, but the liquid water might not be cooling. It probably isn't as that liquid water is having thermal energy (heat) pumped into it by a heat source of some kind. Turn on a burner or element on the range under a pan of water and the water will begin warming until it's boiling. As water boils off, it is taking thermal (heat) energy with it, but the remaining water doesn't cool down as the heat source continues to add more thermal energy.
liquid, cause its in the ocean rivers lakes etc
The state of matter changes from liquid to gas when water is boiled in a pan on a stove.
conditions that might turn liquid water in to solid might be cold degres below zero
water vapor condenses to form liquid water
Why scientists believe a liquid water ocean might exist on the moon Titan
water might be in any form Ice(solid) Water(liquid) Vapour(gas)
Europa
Because europa has the same impact rate as her sister but europa is one of the smoothest planets, meaning there would be water rising and forming more ice making it look like there is no craters.
because liquid mixes in food and water to dissolve
liquid
There is no liquid water now on Mars. There may have been, in the past. Also, there is ice on Mars.
Currently, Mars is too cold for liquid water to exist on its surface. Dry river beds suggest that liquid water once flowed there.
They believe there is liquid water underneath its frozen surface. If there is liquid water on Europa, there might also be life.
There is evidence that there was once water on Mars due to large gullies on its surface. This may suggest that running liquid water may have eroded it away and the fact that Mars has 'frozen' ice caps may suggest that it was once liquid water that had frozen over a large period of time.
