Question

A glass cylinder contains four liquid layers: mercury (d = 13.6 g/ml), chloroform (d = 1.49 g/ml), water (d = 1.00 g/ml), ether (d = 0.708 gml). if a cork stopper (d = 0.50 g/ml) is dropped into the cylinder, where does it come to rest

Answer 1

The answer is : It will come to rest on the top of ether layer.

The explanation:

The lower the density the lighter the liquid and the higher the density the heavier the liquid.

- we here have the density of the cork stopper = 0.5 g/ml , this means ha i has the lowest density as:

mercury (d = 13.6 g/ml), chloroform (d = 1.49 g/ml), water (d = 1.00 g/ml), ether (d = 0.708 gml)

so the layers from the bottom to the top are going to be like that:

-mercury

-chloroform

-water

- ether

- and finally a cork stopper at the top of the ether
