Step-by-step explanation:
A physical change is defined as the change that can be measured or observed easily. In physical change there occurs no change in chemical composition of a substance.
For example, mass, shape, size, density, malleability, ductility etc are all physical properties.
A property in which a substance can be hammered in order to change its shape in the form of this sheets is known as malleability. It is a physical property because it leads to change in physical appearance of the substance.
Hence, we can conclude that a round ball of dough is rolled and flattened into a sheet to make pie crust. Then it means that physical property of the dough which has changed is malleability.
