Basically, someone shone the Batman sign into the sky and Batman saw it so he came and fixed the water supply system.
You can turn steam back into water by condensing it, condensation is a process which changes a gas into water.
Rain
It will turn back into water .
you freeze it XD
Water is water, whether solid (ice), liquid or gas.
Turn off the hot water to your tank and do not use any water -- and leave it off for about 30 min. -- then turn your valve back on and if you hear water going back into tank you have a leak somewhere
condensation
To turn the water back on in your house, locate the main water shut-off valve, typically found near the water meter or where the main water line enters your home. Turn the valve clockwise to open it and restore water flow. If you're unsure or unable to do this yourself, contact a plumber for assistance.
I would assume trap it, and cool it back down
Dirt can turn into mud when it gets wet from water or rain, but when the water evaporates, the mud can dry back into dirt. This cycle can happen depending on the presence of water or other wet conditions.
air in the water lines causes banging and whistles/screams. Turn off main water, turn on the faucet, turn main water back on, and it should force the air out.
