Gravity does NOT * 10 points increase when the distance between two objects increases. increase when the distance between two objects decreases. increase when the mass of one object increases. increase when the mass of both objects increases.

increase when the distance between two objects increases

Explanation:

when the objects move further apart, the gravitational pull between them becomes weaker, and so the gravity isn't as strong. all of the other options increase gravity

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
