Cooking of food will show chemical change.

When we cook food the chemical properties of the food change. And once a food is cooked it cannot be reversed to raw food. That's why it is a chemical change.

Hope this helps you!:)

hi friends

when a substance combines with another to form a new substance called chemical change. in simple language chemical change means irreversible.
 for example, if we burn a paper we will get ask only. it's a chemical change 


Q: Which one of the following will show chemical change:-
a)freezing of water
 b)cooking of food
 c)dusting of black board

freezing of water is reversible so its not chemical change.
cooking of the food is chemical change because it is irreversible.
the dusting of the blackboard is chemical change because it is irreversible.
 
thank you
