Increasing pressure will give a lower freezing point. So if you wish to keep ice cold longer, increase pressure on the ice.
At least one degree above freezing?
No , above ground pools are different in that you can drain them , the reason you cannot drain an in ground pool is because the pool is built to have water pressure , and it is very stressful on the walls , I hope this answered your question :) .
Stick a hose in it and turn the tap on. Keep an eye on it as it fills so you can pull any creases out of the liner before there is too much water pressure on it.
Yes, you will need to keep it above freezing and below 100 degrees F.
The best way to do this is to freeze it. this product will only stay good if kept in the refrigerator for about 5 days. Freezing can keep it for years.
All of the above.
if you put screens to keep birds out of the pipes the moisture from the exhaust will freeze, and the exhaust motor will not be able to vent there by tripping the furnace on a pressure switch fault. the pipes ie intake and exhaust should have a minimum distance of 15 inches apart, and the same above the ground to prevent snow drifts blocking them.
It turn off the compressor to keep the evaporator from freezing up which can cause system damage.
Keep forks 1 foot above ground and do not speed.
First of all, birds should only drink the water in bird baths, not get in it freezing winter weather. To keep it above freezing, there are heated bird baths. For more information check out www.a-home-for-wild-birds.com/bird-bath-heater.html.
No, it will melt. Refrigerators are kept at temperatures a little above freezing. Keep snow in the freezer.
