Which of the following are likely to be physical changes to an object?
tatuchka [14]

Answer:

The correct option is 'd': The change in shape of an object.

Explanation:

Since by definition physical change is defined as a change that changes only the form of an object or substance and producing no change in the chemical composition of the substance. Physical changes are reversible in nature.

As we can see from all the options the change in the shape of the object is a reversible change as we can always remold any substance in any shape, thus it confirms to a physical change.

The change in the molecular composition of an object is a hallmark of a chemical reaction thus indicates a chemical change.

The smell change in an object is an indication of a chemical change in the object hence is not a physical change.
