List a couple of physical properties of iron?

Iron is a lustrous, ductile, malleable, silver-gray metal .

Explanation:

Iron is a lustrous, ductile, malleable, silver-gray metal (group VIII of the periodic table). It is known to exist in four distinct crystalline forms. Iron rusts in damp air, but not in dry air. It dissolves readily in dilute acids.

Hi there! Some physical properties of iron is:

1. Color (Sliver, gray)

2. Malleability (Can it be turned into a shape?)

3. Luster (Can it shine?)

Explanation: Color: Some iron can appear rusty, like black or brown.

Malleability: Can you shape it or bend it? With iron, it's impossible because it's too strong.

Luster: Can iron shine? It depends, but iron doesn't have a glow.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

explanation: no but i do not usually comment
