An increase of temperature is sufficient.
heat the fricken pan
If a cell phone gets wet, remove it immediately from the water and dry it as thoroughly and quickly as possible (use warm air not a microwave oven!). Take it apart as much as can easily be done to make sure that no water remains in the battery compartment or other cavities. You could try spraying or dipping in pure alcohol which will dissolve the water and evaporate more quickly.
You would have to evaporate the water
Desalination of water is not a visual process. It is usually done by some form of distillation. You evaporate or boil the water away, leaving the salt behind.
Yes, through evaporation. Sea salt is taken from the ocean and sold in stores and markets all over the world. It is done by having the water evaporate in beds and when the process is done the beds are all salt. The salt is then broken up into blocks, stacked, and then sold for use in food and cooking.
evaporate the unclean water then cool down the steam and you get clean water, leaving germs and other things behind, but be careful because there is allways the chance other thing will evaporate. PLEASE IMPROVE IF THERE ARE ANY MISTAKES HERE
If it's done quickly enough, the momentum of the water will keep it in the cup if you swing it around.
Spinning removes water via centrifugal force (usually done in the washing machine). Tumble dry adds heat to evaporate remaining moisture (usually done in the dryer).
Nothing
The most simple way is to boil the salty water until all the water is gone. Salt will be left behind. You can also leave the water by a window with sunlight, then wait for the water to slowly evaporate. Unless the salt was in a saturated solution, the salt crystals shouldn't be too much larger than normal.
There is many ways to evaporate water from seawater. The old fashion way is to retain water from the high tie and let the sun evaporate the water. Once done they take shovels and buckets to recover the salt. An other way would be to use an industrial evaporator which can be multiple effect evaporator or mechanical vapor recompression (MVR) followed by a crystallization unit.
the quotation from Shakespears Macbeth is "if it were done when 'tis done, then 'twer well it 'twer done quickly" (Macbeth, act 1 scene 7)
