Water Being Turned Into Ice Cubes In A Freezer Is An Example Of Physical Change.

Water turning into ice cubes in a freezer is one of the most common examples of physical change. Physical changes occur when the form of an object or substance is altered without any changes to its chemical composition. This physical change to water is known as freezing. In this process, the water molecules move from a liquid state to form ice crystals. The ice crystals are held together by hydrogen bonds to form a crystalline solid.

At temperatures below 0°C, the molecules in water become less active and slow down. This is when the phenomenon of freezing starts to occur in the molecules and they start to form ice crystals. This slows down even further until the water has turned into ice. The temperature at which freezing takes place is called the freezing point. It is not necessarily 0°C since different substances have different freezing points.

The process of water turning into ice is a physical change because the molecular structure of the water molecules isn’t altered in any way. This process is reversible as well since melting the ice will revert it back to liquid water. As the temperature increases, the molecules become more active and start to move again, eventually becoming liquid again.

Therefore, water being turned into ice cubes in a freezer is an example of physical change, which is reversible and does not affect the molecular structure of the molecules.
