Step-by-step explanation:
A property that does not bring any change in chemical composition of a substance are known as physical properties.
For example, shape, size, mass, volume, density, hardness etc of a substance are all physical properties.
On the other hand, a property that changes chemical composition of a substance is known as chemical property.
For example, precipitation, reactivity, toxicity etc are chemical property.
Therefore, given changes are correctly matched as follows.
- liquid water freezes into solid ice - physical change
- wood burns to ashes - chemical change
- a window shatters when hit with a rock - physical change
- an old car sits in a junkyard and rusts - chemical change
- a cup of hot chocolate gives off steam - physical change
