A good example would be a person hanging out wet clothing in freezing conditions. the clothes freeze as soon as they are on the line. however the amount of water in the air is far lower then the amount of water in the clothing. and whether the water is frozen or not it will evaporate and the clothes will dry. slightly quicker if there is a breeze. All of a sudden you can see the clothes being moved about by the wind and you know they are dry. I have seen this happen. Indians in the south American mountains used to freeze dry potatoes the same way in the mountains, by leaving them out in dry freezing conditions.
it is a certain products require a porous structures to facilitate dehydration , otherwise they may suffer heat or oxidation damage during drying even at room temperature ..
A warm room will make it dry faster.
Hot water would take longer to reach the freezing point than room temperature so hot water would freeze slower than water at room temperature
Freeze-drying is a method for dehydrating food and other perishable products, like pharmaceuticals, medical supplies and biological samples. The material is first frozen and then placed in a low-pressure chamber so that the ice sublimates. It is the only practical way to preserve things by dehydration without applying heat (which would change the substance irreversibly). Foods dehydrated by freeze-drying can be sealed and safely stored at room temperature for years. When opened, freeze-dried foods can be reconstituted by simply adding water.
Yeah any liquid can and as long as it is in a freezing temperature room or container forever!
It is not possible. You call the substance a solid if it is so at room temperature. It is not possible for a solid (at room temperature) to also be as a liquid at room temperature.
you freeze it then you take it out for 5 or 6 days at room temperature
No, they taste far better when consumed (as intended) at room temperature.
yes, as long as it is cooled to room temperature before freezing.
the elements which are very hot and freeze when very cold ,they are the elements which are gases at room temp.
yes
I usually have the thermostat on72
