Question

Ms. Ramos has a graduated cylinder that shows the volume as 30 ml. She dropped a marble in
and the volume now reads 42 ml. What is the volume of the marble?

Answer 1

Respuesta:

Place the graduated cylinder in a flat surface and match the height of the liquid column directly with the level of your eye. Due to the superficial tension property of the liquid, this will tend to curve downward. This curve is known as meniscus. Read the volume value at the bottom of the meniscus.
