Ideal Gas Laws
« on: February 13, 2008, 12:09:22 PM »
What will happen to each gas law variable when an inflated balloon is placed in liquid nitrogen?

I think its: T will go down, n does not change, but I'm not sure what happens to V.

Any comments or help?

treat it like an algebraic equation. 

If 2x = 3y and you doubled y.  how would x change?  how does that relate to your (correct) assertion that temperature will drop w/ liquid nitrogen?

Do you know what the temperature of liquid nitrogen is?  You don't need it to answer the question, but it's interesting to know nonetheless.

You can use that algebraic approach to explore what happens to any variable in the IGL when any other variable is changed.

If 2*3 = x*y,  what happens to x if you double y?  What happens to pressure if you lower the volume?
