Which substance freezes at lowest temperature?
That’s due to the fact that Helium has the lowest boiling and freezing points of any other known substance. Helium happens to be the only element that can’t be solidified or frozen at normal atmospheric pressure. Only once you apply a pressure of 25 atmospheres at Helium’s freezing point of −458 °F can you solidify it.
What substance freezes in winter?
Pure water freezes at 0°C. Water with substances dissolved in it (a solution) freezes at a lower temperature. Some substances, such as candle wax, freeze (solidify) at temperatures above 0°C. Other substances, such as vegetable oil, freeze at a temperature below 0°C.

At what temp does co2 freeze?
-109 degrees Fahrenheit
Carbon dioxide is a gas at room temperature, and it freezes solid at a much lower point than water: -109 degrees Fahrenheit (-78 C).
Does water in trees freeze?
Trees are about half water, maybe a little less in winter. And if the temperature drops low enough, the water in even the most cold-hardy tree will freeze. Since ice crystals can shred cell membranes, a hard freeze can be devastating to living tree cells, leading to dead leaves, branches, and even whole trees.
