The diagram below represents two beakers, each containing an ice cube and clear liquid. in beaker a the ice cube floats, and in beaker b the ice cube rest on the bottom. what is the most probable cause for the difference in behavior of the ice cube in the two beakers?

The density of the liquid in beaker B is less than the that of ice.

Explanation:

Ice will float if its mass is less than the mass of the liquid it displaces.

For example, the density of ice is less than that of water.

A 10 cm³ cube of ice has a mass of about 9 g, while the mass of 10 cm³ of water is 10 g. Thus, 9 g of ice displaces 10 g of water.

The denser water displaces the lighter ice and the ice floats to the top.

If the density of the liquid is less than that of water, say, 8 g/cm³, the ice will displace only 8 g of the liquid. The ice will sink.

we need the questions , i may then you.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
