What is the purpose of the little hair inside the nose?
They're there to help trap dust particles - to stop them going into the lungs.
What happens when pressure is lower inside the lungs than outside the lungs?
When pressure inside the lungs is lower than outside, air flows into the lungs to equalize the pressure. This is known as inhalation, where the diaphragm contracts and the rib cage expands to create more space for air to enter the lungs.
Why cant particles and microorganisms get into the lungs?

What happens to the lungs when they are exposed to dirt and chemicals?
The lungs become black and breathing becomes hard. The lungs are protected by a series of defense mechanisms in different regions of the respiratory tract. When a person breathes in, particles suspended in the air enter the nose, but not all of them reach the lungs. The nose is an efficient filter. Most large particles are stopped in it, until they are removed mechanically by blowing the nose or sneezing.
Why does the lung collapse if intrapleural pressure is not maintain?
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
What sort of things could make the lungs dirtyHow do these things get into the lungs?
A dusty enviroment can affect our lungs when we breathe it in because the dust particles can get trapped in our lungs which would affect our breathings the particles travel through the the air and we inhale it!

Why is it that inside of a nose is warm and moist?
Our lungs are quite sensitive. The blood vessels in the nose warm the air to a temperature close to our own. The moisture is simply secretions designed to trap foreign particles such as pollen and dust - to sopt them reaching the lungs.
