answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
