Answer:
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 .
