Yes, ice expands as it freezes. This expansion is due to the unique hydrogen bonding structure of water molecules in its solid form, which causes them to be less densely packed compared to liquid water.
Ice freezing in a crack of a rock is considered weathering.
It depends. If the ice crystals are forming, then yes, the water is freezing. If you just mean ice crystals, just there not doing anything, then no.
Adding salt to ice lowers its freezing point, causing the ice to melt. This process is called freezing point depression. The salt disrupts the ability of water molecules to form solid ice crystals, resulting in a colder mixture that can be used for freezing-point experiments or making ice cream.
This can be used as a lubricant or a coolant at a temperature below freezing of water, but above the freezing point of the liquid. Also, when ice freezes on sidewalks, salt is spread to prevent slipping on the ice.
bye when it is freezing out
becuse the molecules are spread out
because it is very spread out in the molecular structure
salt and ice are the freezing mixtures of ice.
Freezing water of is an example of physical change.
The mass of ice after freezing will be the same as the mass before freezing. The volume however, will be greater as ice than it was as liquid water.
Yes. The freezing point of water (melting point of ice) depends on both the temperature and the pressure. One easy way to lower the pressure is to add salt to ice. This lowers its freezing point and caused it to melt. Salt is spread on street and sidewalk ice in some areas to melt it and the addition of salt to ice is also used in the cooling of ice cream.

salt products lower the freezing point of moisture on the road surface, so ice or snow that has already formed will melt and will prevent more ice forming.
Salt and IceHow does salt "melt" snow and ice? As we know, pure water freezes at 0 °C. Any impurity that is added to the ice interferes with the freezing process, and water does not become solid ice until the temperature drops even lower. As a result, adding any dissolved impurity such as salt lowers the freezing point of water. Instead of freezing at 0 °C, a mixture of 20% salt in water stays a liquid until the temperature is as low as -16 °C.-- answer by Divine Crow. (Credits to NELSON: Science Perspectives 9)
Freezing is a physical process.
Ice forms from the freezing of water.
