Evaporation
melting
the formation of water in a car engine cannot be chnaged bakc to its original state. If you melt ice, it can be turned back into ice. A chemical change cannot be turned back into its original form. But a physical chnage can be turned bakc into its original form.
Ice has expanded when it turned from water into ice. Ice floats. This shows that the density of the ice is less than water.

no as it can be turned back to water or be freeze to ice by over cooling.
a physical change called melting. It is also called a phase change.
The change from ice to water is a physical change defined as melting, this reaction occurs when ice exceeds a temperature of 32 degrees Fahrenheit (0 degrees Celsius.)
Yes, the water has turned into ice. It was a liquid but it is now a solid. You can change it back again by melting it.
Yes, ice melting is a physical change.
Freezing of ice is a physical change as ice can be turned back to water by heating. It has retained its chemical properties and underwent only a physical change (changing shape from water to ice). Hence it is a physical change.
Physical change
Ice melting is a physical change. It occurs when a solid (ice) turns into a liquid (water) due to an increase in temperature. The chemical composition of water remains the same during the process.
