water
Things freeze in dry ice because dry ice is solid carbon dioxide that is extremely cold at -78.5°C (-109.3°F). When an object comes into contact with dry ice, heat is transferred from the object to the dry ice, causing the object's temperature to drop rapidly and freeze.
For optimal effectiveness, freeze an ice pack for at least 2 hours before use.
Ice packs typically take about 4-6 hours to freeze completely in a standard home freezer.
You will have roughly the same amount of ice as the amount of water you started out with, so probably about 5 mL of ice.
First, you need to boil the water you're using in order to remove impurities. Then, freeze it again, and fashion the ice into a lens in order to focus sunlight on some dry tinder. It isn't easy, but it is possible.
it is about 200 degrees
Freeze=0 Boil=100
Freeze : 0 Boil : 100
It is simply air bubbles trapped in the ice. Boil water, let it cool, then freeze it. The ice should be completely clear.
Melted ice is liquid water and water boil.
ice can freeze any liquid and some solids
When you freeze water, you create ice.
No.
You can boil it or you could freeze it.
hot or cold air
Yes!!! You can freeze any liquid. However, different liquids freeze( and boil) at different temperatures.
last time i checked, ice can't freeze. i believe you mean water?
