Question

What is the relation between density and pressure of an ideal gas

Answer 1

the relationship between density and pressure is that as the pressure of any substance increased , its density also increases because it's particles comes much closer to each other than normal. Similarly, when pressure on any substance is decreased it's density also decreases because it's particles move further from each other than normal.
Hence, we can say that density of any substance is directly proportional to the pressure applied on it.
