An intensive property is a physical quantity whose value does not depend on the amount of substance which was measured. The most obvious intensive quantities are ratios of extensive quantities. In a homogeneous system divided into two halves, all its extensive properties, in particular its volume and its mass, are divided into two halves. All its intensive properties, such as the mass per volume (mass density) or volume per mass (specific volume), must remain the sa…
WebIf heat is evolved during a change (is released) the change is exothermic. If heat is needs to be supplied, the change is endothermic. An important distinction, is that heat is energy that flows due to a temperature difference, while temperature is a measure of the average kinetic energy of the molecules in a substance.
