Is ice physical or chemical change?

1: Ice Melting is a physical change. When liquid water (H2O) freezes into a solid state (ice), it appears changed; However, this change is only physical as the the composition of the constituent molecules is the same: 11.19% hydrogen and 88.81% oxygen by mass.

Why melting ice is a physical change?

As an ice cube melts, its shape changes as it acquires the ability to flow. However, its composition does not change. Melting is an example of a physical change .

Is making ice cubes a physical or chemical change?

Physical changes can be reversible in some cases. One example is making ice cubes. If you freeze liquid water to ice, it can melt back into a liquid again (assuming you allowed the temperature to change, say by taking them out of the freezer!). The molecular structure remains the same, only the form has changed.
