If you were stranded in the desert and wanted make water vapor could of the air so that you could drink it what should you do

I think you forgot to give the options along with the question. I am answering the question based on my research and knowledge. "You should remove heat energy because air is a gas and particles need to slow to become a liquid" is the way you can make water for drinking in the desert. I hope it helped you.

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water
