When a liquid is frozen, does it become even harder when it gets even colder?

Answer 1

Most materials become harder and more brittle as the temperature drops. Carbon steel and rubber are famous for this. But there are some metals for which this is not the case. 300 series stainless steels remain strong and flexible. High purity copper and indium remain soft and ductile even at a few degrees Kelvin. They are often used to make pressure and vacuum gaskets in cryogenic hardware for this reason.

Answer 2

Yes, to a certain point, and beyond that point it will not get harder??? Any science geeks around to definitively answer this?

Answer 3

if the liquid is water it will have maximum density upto 4degree celcius .on further decreasing the temperature it expands(anomalous property) because of which it becomes less dense . so whether the liquid becomes harder or not depends on whether it has anomalous property or not.

Answer 4

Yes, old icebergs are harder than young ones.
