Question

I completely forgot about my study guide and need to get it in asap!! Please help.


Sensors detect the concentration of mercaptan molecules in natural gas at various distances from a leaking source. At which location will a sensor detect the highest concentration of mercaptan?

one-half meter in front of the source

one meter in front of the source

one meter behind the source

two meters behind the source

Answer 1

As molecules leak out they spread out. As you get further and further from the initial point of leakage, the average distance between molecules increases and the concentration drops.

Answer 2

I still dont know which one it would be (/.\)
