Will the tiny air bubbles seen before the water actually boils,also appear if we do this activity by reheating boiled water kept in an air tight bottle?

Bubbles are observed because on heating , the air which is already present in the water in dissolved form tends to escape from the water.This will also take place if we boil it in an air tight bottle .

tiny bubbles are formed when air present in the water escapes on boiling it . Water after boiling if kept in air tight container and then re boiled bubbles wont form due to absence of air
