Question

Respected sir
please give me a good answer for my question

clay is moulded into different shapes it is soft .when it is baked it is hard. Is it a chemical change or a physical change? How?

Answer 1

clay is thick, brown, and soft. A physical change happens when matter changes size, shape, or form. You can make physical changes to clay by molding it into a pot or flattening it out. The substance is still clay—its shape is just different. The substance also has some of the same properties.


When it is baked, it loses the properties of clay.
We can not module it to differant shapes atter it is baked.
Since all the properties has changed, it is a chemical change.
