Answer:
Two physical properties that would allow differentiation between copper, lead and iron shot are - <u>Color</u> and <u>Density </u>
<u>COPPER -</u> <u>Color -</u> Copper has a<u> reddish brown color .</u>
<u> Density -</u> Density of copper is<u> 8.96 </u><u></u>
<u>LEAD </u>- <u>Color -</u> Lead is <u>grey</u> in color.
<u>Density</u> - Density of Lead is <u>11.34</u><u />
<u>IRON SHOT -</u> <u>Color-</u> Iron shot is in <u>grey color with extra shine .</u>
<u> Density -</u> Density of iron shot is <u>10.49 </u>
Explanation:
COPPER- Copper (Cu) is a reddish, highly ductile metal that belongs to Group 11 (Ib) of the periodic table and is a particularly excellent conductor of electricity and heat. Copper is found in nature in its free metallic state.
LEAD- Lead (Pb) is a soft, silvery white or grayish metal in Periodic Group 14 (IVa). Lead is a weak conductor of electricity and is very malleable, ductile, and thick. Lead, which has been known since antiquity and is considered the oldest of metals by alchemists, is extremely durable and corrosion-resistant, as evidenced by the continued use of lead water pipes constructed by the ancient Romans.
IRON SHOT - Small round iron balls used as projectiles are known as iron shot. Balance scales are used with simple weights. Iron balls are used in the shot put competition.
<u>Hence , the differentiation is mentioned in the above answer.</u>
