Why do you think Mars does not have liquid water on its surface today?

The boiling point of water is 100 degrees celsius at 1 bar of air pressure, and the boiling point decreases as one gets higher (and the pressure is lower). On mars the air pressure is 7-9% that of the Earth's, meaning that if you melt ice it would immediately turn to water vapor.

∙ 11y agoI will assume you mean liquid water. The low temperature is one reason.
There probably was water in the past, when conditions were different.
Also the low gravity and low atmospheric pressure mean water would
soon evaporate and disappear into space.

∙ 14y agoThe average atmospheric pressure and temperature on Mars are too low to sustain water in the liquid form. It will freeze immediately.

∙ 12y agoit's too cold so it freezes and that's why mars has polar ice caps

Can water exist on a planet with no atmosphere?
Atmospheric pressure is an important factor in keeping liquid water on the surface of a planet. With no atmosphere, liquid water would quickly escape into space. It would depend on various factors such as the temperature and escape velocity of the planet of course. Scientists think liquid water existed on Mars in the past when the atmosphere was a lot denser. Water does exist on the surface Mars, but only as ice.
Is there any liquid water in the moon?
no Not on the surface; some speculate that there may be frozen water beneath the surface.
It is too cold for liquid water to exist on the surface?
C.Europa
Which moon is too cold for liquid water to exist on the surface?
europa
Which of Jupiter's moons possibly contains a liquid ocean under its surface?
Europa is the moon that could possibly contain a liquid ocean under its icy surface, and it could possibly be liquid water, or H2O!
What makes us think that mars must once have had an atmosphere that was warmer and had higher surface pressure?
The atmosphere is too cold and thin for liquid water today, yet we see evidence that water flowed on the surface in the past.
What is the answer for the process by water on earths surface changes from liquid to water vapor?
transpiration,i think
Do astronomers think there could be life on europa?
They believe there is liquid water underneath its frozen surface. If there is liquid water on Europa, there might also be life.
What is the process called when fast moving molecules break away from the surface of liquid water to from water vapor?
evaporation i think but i am not sure

It is too cold for liquid water to exist on the surface
When condensation occurs water changes from what?
Gas (water vapor in the air) to liquid (on the surface).
