Why is density a physical property but volume isn’t?

Density is a physical property but volume isn’t because density is intensive property but volume is extensive property.    

Explanation:

EXTENSIVE PROPERTY- A property of matter like volume and mass which depends on the amount of being measured is called extensive property.

INTENSIVE PROPERTY- A property of matter like colour and density which does not depend on the amount of the substance present is called intensive property.

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
