Give reasons :
1. Curdling of milk is an irreversible change.
2. Cooking of food is an endothermic change.
3. Baking a chapatti is a chemical change.
4. Dissolving is a physical change.
5. The process of freezing can be easily reversed.
6. The rate of evaporation decreases with increase in humidity.

Explanation:
because curd is formed from milk and we can't get the milk again
because curd is formed from milk and we can't get the milk again bakingo chapati is a chemical change because chapatis formed from flour and water so we can't get the flour and water again
because curd is formed from milk and we can't get the milk again bakingo chapati is a chemical change because chapatis formed from flour and water so we can't get the flour and water again dissolving is a chemical change because we can get it by evaporation again for example if we dissolve sugar in water we can evaporate it and then we get sugar again and water get condensed
