and the same bottle is then filled with water (up to the surface of the bottle)
is the volume of water and the liquid same??

Answer 1

Answer:

Put a small hole near the bottom of the water bottle using the nail. Be careful! Push it through or tap it in with a hammer

Put a small hole through the lid of the bottle with the nail (you will probably have to tap this through with a hammer, the plastic is thicker)
