Question

Which of the following abilities is NOT a physical property of matter?

Answer 1

Answer:

Ability to react chemically with other substances is not a physical property.

Explanation:

The ability to dissolve in other substance can be both physical and chemical property.

It depend upon the type of solute, solvent and reaction between them.

For example, if NaCl is dissolved in water it gives sodium and chloride ions which are behaving different from the original compound. it will be chemical change but if water is evaporated it will give back sodium chloride and than it will be a physical change.

But if dissolved substances make the mixture not compound it will than a physical change, and solubility will consider a physical property.

Physical properties:

The properties which are not associated with change in chemical composition are called physical properties.                                                                                          

Example

Density, color, hardness, conductance, melting point, boiling points all  are physical properties.

Chemical properties:

The properties which are associated with change in chemical composition are called chemical properties.        

Example:

Toxicity, flammability, heat of combustion etc.

Combustion of fuel or wood: that oil or wood convert into energy, CO2 and ash in case of wood

The reaction of Hydrogen and oxygen:

H 2 (g)  + O 2  (g) -------------------------------------> 2H 2O  (l)
