Can anyone just give me a basic example I can use in a presentation?

I think your on the wrong website... or at least the wrong forum. Google is over there somewhere ---->>>
and the homework help section is just around the corner.

wat

its a question about physics, y u trollin here?

Why don't you write about how Charle's Law may or may not affect the adiabatic lapse rate?

PV = n*R*T

as T increases, P*V must increase. Think about the air in your tires. When your car hasn't been driven in a while, the air inside them is "cold" and you have a certain pressure (probably 30 psi, don't know what it would be in Pascals though, or if other countries still use psi or what). However, if you check the pressure in your tires after you've been driving for a while, you'll notice the pressure has increased (the first time I did this, the pressure increased from 30 psi to 38 psi). This is because the temperature of the air inside has increased, and so P*V must have increased. V remained constant (the size of the tire didn't change), so the air pressure increased.

So there's your real-life example. Because the pressure in your tires increases as you drive (the air molecules inside the tire collide with each other as you drive and that increases the average kinetic energy, i.e. the temperature), tires need to be built to contain a wide range of pressures.

i think u need to stay awake in your classes bro.

Fuck, Charles Law is the Ideal Gas Law, but assuming P is constant... lol you're probably right.

Thanks anyway, just made up an example using a balloon
