Any change that does not affect the chemical composition of a substance is called physical change.

Any change that occurs by affecting the chemical composition of a substance resulting in the formation of new substance by the rearrangement of the atoms is called chemical change.

The property that is related to the physical state of a substance is termed as a physical property. These properties are used to describe matter.

The property related to the change in the chemical composition of a substance is termed as a chemical property.

When a substance sublimes it changes its state. The chemical composition of the substance remains the same.

Therefore, sublimation of dry ice is a physical change.

The given change corresponds to a physical property.

Answer to Problem 1.1P

Solution:

The hammering of copper wire is a physical change and it corresponds to a physical property.

Explanation of Solution

Any change that does not affect the chemical composition of a substance is called physical change.

Any change that occurs by affecting the chemical composition of a substance resulting in the formation of new substance by the rearrangement of the atoms is called chemical change.

The property that is related to the physical state of a substance is termed as a physical property. These properties are used to describe matter.

The property related to the change in the chemical composition of a substance is termed as a chemical property.

When copper wire is hammered flat, only the shape of the wire is changed. Since, there is no change in the chemical composition of the wire, it is a physical change.

Ability of a substance to flatten into a thin sheet by hammering is called malleability.

Malleability is a physical property.
