Intensive

Intensive magnitude is indivisible quantity as degree. It has no parts, is not addable. Examples: temperature (Ch. 21°C + 10°C ≠ 30°C when mixed), pressure, density, pain, color. Degree is reflected in itself --- the whole in one point. Intensive magnitude arises from extensive: the derivative (rate) of an extensive quantity is intensive (velocity = dx/dt). It turns back into extensive: high temperature can bring about extensive expansion. In thermodynamics: intensive quantities are independent of system size.
