keep it in a hot place
Keep warming
In the thermos
keep it cold. keep it in a good container. glass or plastic should do. but i don't think wood would be a good thing to store water in. keep it air tight or mold and bacteria will grow.
put it in a freezer
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.
ice
it is to keep you safe
because steel is goood
The water will eventually evaporate, leaving a dry, empty glass. Any Impurities or dust in the original water will remain as a slight staining on the glass. If the glass of water had stood in bright sunlight, algae may have formed, making any staining greenish in colour.
If you burn a peanut it will keep aflame for a long time underwater, and boil the water
No, It doesn't. If you want to keep hot water hot for a longer time use a polystirene cup.
Evaporation - to change into vapor. For example, if you leave a glass of water sitting out for a long period of time, the water will eventually evaporate and disappear.
i wouldn't keep water in a water tank unless it has a purification system installed on it i would think it would have to be installed by a professional water tank installers ,so if i did i knew it would be safe to keep for long periods of time
i think that its not psuedo its pseudo ..so the solids wihch are not real....they are actually liquids.for eg glass we see that the glass is a solid but if we keep for a long time it melts and transforms into a liqiid
