What is physical property?
A physical property is a property of matter that can be observed and measured without changing the sample's chemical identity.
(a). Physical state:
Solid iron coils
All metals are solids at ambient temperature except for Mercury and Gallium.
Shiny gold metal
Metals have a high lustre (named metallic lustre).
Hard iron metal rods
The majority of metals are tough and durable (exceptions: Sodium and Potassium can be cut with a knife)
(d). Melting point and Boiling point:
Highly melted metal
Metals usually have high melting and boiling points, and they evaporate only at high temperatures. (exceptions: Gallium, Mercury, Sodium and Potassium).
High density metal used in train wheels
Metals possess high density (exceptions: Sodium and Potassium are less dense than water).
Metal wire used in the bridge protection wall
Generally, metals are ductile. They are capable of being drawn into thin wires without breaking.
Metal sheet used for roofing
Metals are usually malleable, i.e., metals can be beaten into thin sheets without cracking (except Zinc and Mercury).
(h). Conduction of heat and electricity:
Metal wire used in electricity
Metals are the best conductors of heat and electricity; silver and copper are particularly good in this (exception: Tungsten).
Metal under the water does not dissolve
Metals do not usually dissolve in liquid solvents.
