Answer 2

In a physical process (d) substance does not change.

What is the physical change?

• An adjustment in which a substance goes through an adjustment of its actual properties is known as a "physical change."
• A physical change is, by and large, reversible.
• There is no new substance formed as a result of such a transition.
• For example, the shape, size, variety, and condition of a substance are called its physical properties.
• When there is an adjustment to these properties, it is called a "physical change."

Conclusion:

A physical change is a brief change wherein no new substance is framed and the properties continue as before, despite the fact that a portion of its properties like tone, state, shape, size might change.
