For wach of the following cases, state whether the density of the object increases, decreases, or remains the same:

(a) A sample of chlorine gas is compressed

(b) A lead weight is carried up a high mountain.

(c) A sample of water is frozen.

a) increases.

b) remains the same.

c) decreases. the hydrogen molecules constrict or shrink from actual size!

Explanation:

Since,

Density is given as mass divided by the volume.

(a) As the Chlorine gas is compressed, the molecules of gas comes close to each other, and hence, the density increases.

(b) When the lead is taken to high mountain, its density remains the same, as density is independent of higher pressure, as going to mountain will increase the pressure.

(c) As the water is freeze, its density decreases,

Because ice is less dense than water, as seen, the ice ice can float on the surface of water.
