Question

Define density. From the concept of density explain why iron balls sink in the water whereas cotton balls float. What do you mean by good and bad conductors of heat and electricity? Give examples of two materials from each category

Answer 1

Answer:

DENSITY IS THE RATIO OF MASS AND VOLUME.

IT MEANS THE BODY ACQUIRING MASS PER UNIT VOLUME.

IRON BALL SINKS BECAUSE ITS DENSITY IS MORE THAN WATER. WHEREAS COTTON BALLS HAVE LESS DENSITY BECAUSE OF LESS MASS SO THEY FLOAT.

GOOD CONDUCTORS ARE THOSE WHICH HAVE LESS RESITANCES AND ALLOWS CURRENT TO FLOW EASILY eg. IRON

BADCONDUCTORS ARE THOSE WHICH HAVE MORE RESISTANCES AND DOESN'T ALLOW CURRENT TO FLOW EASILY. EG WATER
