Delanda's Intensity

When I heard Delanda speaking about intensity he also mentioned critical mass. When the temperature of water reaches a certain point it changes state. There is something more critical occurring at 32 than at 42 deg F. If extensive relationships are measurable, quantifiable, then there can be moments in that quantification where the quality is measurable, thus the moment of intensity. Is that a legitimate reading? Intensities occur through extensive relationships at key moments? Intensity is then the dependent variable while extensities are independent?
