Melting ice into water serves as an example of a physical change, involving a transformation in state without changing the chemical composition of the substance.
A physical change involves altering the form or state of a substance without changing its chemical composition. An example of a physical change is the process of ice melting into water. In this transformation, the water molecules remain the same, but the arrangement changes from a solid to a liquid state. The temperature plays a crucial role, causing the ice to absorb heat energy and transition into a more fluid form. This change is reversible, as cooling the water can reverse the process, turning it back into ice.
Physical changes are characterized by modifications in the physical properties of a substance, such as size, shape, or state, without any new substances being formed. Other examples include cutting paper, dissolving sugar in water, or bending a metal rod. These changes are distinguishable from chemical changes, where the composition of the substance is altered, leading to the formation of new substances.
In summary, an example of a physical change is the melting of ice into water, wherein the substance undergoes a change in state without any alteration in its chemical composition.
