Yes. The melting point of salt solutions is lower than that of pure water.
Physical, its still salt but in a different state
It is a Physical change because it is dissolving the salt and melting the snow both reversable processes
No- it causes a physical change (melting) but it is still salt and water, and if the water evaporates, leaves the salt behind, unchanged.
This is a physical change, a freezing point depression.
Salting ice is a physical change.

No, melting ice is a chemical change where as carving ice is physical.... Another example is chewing food is physical where as enzymes in your saliva breaking down the food is chemical.
The melting of ice is a physical change, a change from the solid phase to a liquid phase by adding heat energy. The water can be refrozen into ice again, because it is the same chemical compound, H2O.Melting does not change the chemical elements in the ice (water), only their molecular form.Frozen water turns to liquid water. It is still water, so melting would be a physical change.
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
salt lowers ice's melting point
Physical changes is change in property. Ex) change from solid to liquid....ice to water. Chemical change changes to different substances. Ex) rotting of fruit.
yes
Salting the highway is a physical change. No chemical reaction occurs. The salt only depresses the freezing point of the ice.
physical change because by adding salt you are lowering its melting point thus can melt the ice at low temperature.
melting ice a physical change
Melting ice is a physical change because it does not change the chemical composition of the water.
its both a chemical change and a physical change.
No. It is a physical change. The chemical formula for water is H2O, and that is also the chemical formula for ice. So there is no chemical change taking place, only a change in the state of matter.
melting ice a physical change
its a chemical change
Nope - ice and water both have the same chemical formula. The only change is with temperature.
It is a physical change. It is still the same substance.
Melting ice is a physical change, because there is no new substance formed. The only thing that changes is the state of matter.
