Answer 1

Answer:

1. Physical change 2. Chemical change

Answer 2

The types of changes each of these steps represent are - 1:Physical change, 2. Chemical change.

Step 1:Mix flour.water eggs, water and milk in a bowl.

When flour, water, eggs, and milk is added and mixed in a bowl, no chemical change occurs. All the individual constituents retain their properties. Hence, this is a physical change.

Step 2:Place the batter in a baking tray and bake a cake in the oven.

As heat is applied to the batter, the constituents will undergo a chemical change, which is why chemical change occurs while baking the cake in the oven.
