Things have gotten bad enough that glaciers are practically on the edge of extinction. 				 It's a physical change because no new substance is produced. Join now. Number 5 Car A car is an example of physical science because it needs gas to work. This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. The water melting has changed the shape and therefore it's physical properties, but the chemical nature of the water has not been altered. Moreover, no new chemical substance is formed in the process and this change is reversible. Ice has a rigid hexagonal crystalline structure because of hydrogen bonding. About 20,000 years ago, much of Europe, Asia, North and South America was covered by huge sheets of ice, each many kilometres thick. The shape of the object has changed.
