Yes. The melting point of salt solutions is lower than that of pure water.
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 highways results in a physical change because the salt dissolves in water to form a solution. This process involves a change in phase without altering the chemical composition of the salt itself.
physical change because by adding salt you are lowering its melting point thus can melt the ice at low temperature.
Melting ice is a physical change. It involves a change in state from solid to liquid without altering the chemical composition of the ice.
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.
No ice melting is a change of state from solid to liquid.
Ice melting is a physical change.
