If it is the average distance irrespective of length of path and of number of impacts we should be justified in ascribing the effect to density, but if it is the number of impacts it would be more reasonable to ascribe it to pressure.
Applying this notion to benzene, let us consider the impacts made by the carbon atom (I) which we will assume to be doubly linked to the carbon atom (2) and singly linked to (6), h standing for the hydrogen atom.
It took a fact-finding visit to the Arctic to see for himself the impacts of climate change.
In the first unit of time, the impacts are 2, 6, h, 2; and in the second 6, 2, h, 6.
These deliver pragmatic, appropriate, transparent actions leading directly to positive impacts.
