Question

Why are the marked lines on a beaker like this useful for measuring the volume of a liquid? A liquid maintains its shape in the beaker, so the beaker can measure the liquid’s height, and the height cubed equals the liquid’s volume. A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume. A liquid is usually made of neutral atoms, and the beaker does not add or remove energy from the atoms, thereby preventing ionization. A liquid is compressible, but since the beaker does not have a top on it, the liquid will maintain its same volume THE ANSWER IS (B)

Answer 1

Answer : Option B) A liquid conforms to the circular area of the beaker, and this area multiplied by the liquid’s height equals its volume.

Explanation : When a liquid is poured into a beaker the liquid takes the internal shape of the beaker which is circular in shape, according to the markings on the beaker one can measure approx quantity of fluid required and perform the experiment. The area of circular of the beaker when multiplied with height of liquid gives the total volumes of fluid present in it.
