The a answer is option C because in process 1 he is shaping so it's a physical change when it's a physical change it is always a reversible change.
in process 2 it's a chemical change because now the pot can't be shaped again because it's baked . whenever it's a chemical change its an irreversible change
in process 2 it's a chemical change because now the pot can't be shaped again because it's baked . whenever it's a chemical change its an irreversible change

A potter shapes pots out of clay (Process 1). He then bakes the pots i...
Explanation:
Process 1 involves shaping pots out of clay, while process 2 involves baking these pots in an oven. Let's analyze each process separately to determine the correct statement.
Process 1: Shaping pots out of clay
- This process is a physical change because the clay is being molded into a different shape, but its chemical composition remains the same.
- It is a reversible change because if the potter decides to reshape the clay, it can be easily done by applying pressure and remolding it.
Process 2: Baking the pots in an oven
- This process involves subjecting the pots to high temperatures in an oven.
- Baking the pots in an oven causes the clay to undergo a chemical change called "firing." This chemical change is irreversible because it permanently alters the chemical composition of the clay.
- During firing, the clay undergoes a process known as vitrification, where the clay particles fuse together, resulting in a solid and durable ceramic material.
- The high temperatures cause the water present in the clay to evaporate, and the clay minerals undergo chemical reactions, resulting in the formation of new compounds.
- These chemical changes cannot be reversed by simply cooling down the pots or applying pressure.
Correct Statement:
Based on the explanations above, the correct statement is:
c) Process 1 is a reversible, physical change while process 2 is an irreversible, chemical change.
Process 1 involves a physical change because the clay is being reshaped, but it is reversible as the clay can be remolded.
Process 2 involves a chemical change because the clay undergoes irreversible chemical reactions during firing, resulting in the formation of a new material with different properties.
