An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is
