Why do cookies dissolve in milk?

Answer 1

For something to dissolve the molecules have to interact. When the milk is hot its molecules are moving faster and they have more energy. This means:

a/ The milk molecules are moving faster (on average) so they will move further each second and therefore bump into the sugar molecules more often.

b/ The milk molecules are more likely to dissolve a sugar molecule when they bump into them. The reason for this is a bit complex and involves quantum mechanics but if we simplify a lot think of it as throwing marbles at a piece of polystyrene. If we throw a marble slowly it is likely to bounce off without damaging the polystyrene, if we throw a marble hard it is likely to chip off a bit of the polystyrene. Replace marble with milk and polystyrene with sugar and you have a simplified model.

Answer 2

the cookies are bread and the milk is wet so they desolve

Answer 3

because of the nutrients
