Question

1. When measuring the volume of an irregularly shaped solid, for the most accurate result, the liquid used should be...

Select one or more:

a. the same density as the solid

b. less dense than the solid

c. more dense than the solid

2.Liquid X is placed into a clear container. You begin adding Liquid Q to the same container. What would happen if Liquid X is more dense than Liquid Q?

Select one or more:

a. They will form layers, with Liquid Q on bottom

b. They will form layers, with Liquid Q on top

c. They will form layers, with Liquid X on top

d. The liquids will mix and form no discernible layers

Answer 1

Solution :-

#1) While measuring the volume of the irregular object the liquid used should have a lower density than the object so that the object can sink in the liquid and displace the volume of the liquid which is equal to the volume of the object.

Therefore the answer is option b) less dense than the solid

#2) Liquid x has more density than liquid Q therefore when they are added in the same container

Since the density of the liquid X is more than the density of liquid Q, therefore, added liquid Q will float on the liquid X and therefore they will form two layers in which liquid Q will be on the top.

Therefore the answer is option B
