Will the tiny bubbles seen before the water actually boils, also appear if we do this activity by reheating boiled water kept in an air tight bottle?
Answers
Answer:
Answer: Bubbles are seen because on heating the water, the air which is already present in it, in dissolved form tends to escape out. Water after boiling if kept in air tight container and then rebelled, there will no bubbles due to the absence of air.

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.
