Property
observation
color dull gray
density 11.3 g/cm3
volume of sample 3 cm3
melting point 327°c
reaction with air lead oxide forms on the surface
electrical conductivity conducts some electricity

which statement is true with respect to the investigation?
a.) the student investigated only the physical properties of lead.
b.) the student investigated only the chemical properties of lead.
c.) the student investigated more physical properties than chemical properties of lead.
d.) the student investigated more chemical properties than physical properties of lead.

The correct option is C.

Explanation:

Physical property is defined as the property which can be measured and whose value describes the state of physical system. For Example: State, density etc.

Chemical property is defined as the property of a substance which is observed during a reaction where the chemical composition of the substance gets changed.

Color : Dull gray  (Physical property)

Density : 11.3 g/cm3   (Physical property)

Volume of sample : 3 cm3   (Physical property)

Melting point : 327°C   (Physical property)

Reaction with air : Lead oxide forms on the surface   (chemical property)

Electrical conductivity : Conducts some electricity (chemical property)

Student have investigated and observed four physical properties and two chemical properties of the sample.
