The density of a 10 pound gold brick is 19.3 g/cm3. What is the density of
a 5 pound gold brick?
A.19.3 g/cmº-The two bricks have the
same density

B.9.6 g/cm3-The 5 pound brick has half
the density of the 10 pound brick

A.19.3 g/cm³-The two bricks have the  same density

Explanation:

The 10 pound gold brick and 5 pound gold brick will have the same density value.

Density is an intensive property and it does not depend on the amount of matter present.

All pure samples of substance will have the same value of density. This is regardless of their masses or volume.

Such a property is called an intensive property.

answer; /// i do believe that the correct answer is (a) boiling

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
