Q7. A fizzing sound was overheard shadowed by the rushing out of bubbles from the bottle dipped in hot water. There was also a sound perceived in the bottle to be found in cold water but not as much as in bottle A.

Q8. There was amassed gas inside the bottle.

Q9. The hot water surges the temperature of the soda drink inside the bottle. As the temperature increases, more gas is accumulated inside the bottle. This reasons the fizzing sound.

Q10. The observation in the bottle of cooking oil is not the same as in the soda drinks.

Q11. There was little gas out in the bottle of cooking oil for the reason of its structure. We know that soda drink is carbonated. The great temperature free the gas from the soda drinks.
