This
assignment has two parts:
1: Modifications
to the Ideal Gas law:
·
Do some research on the 'corrections' to the Ideal gas law
(Hint: van der Waals).
·
Why do we need them? What impact do they have?
Why can we often neglect them? (i.e., answer quantitatively for a particular gas.
What % change they would make in a calculation around standard temperature and
pressure?)
·
Also, look up the constants 'b' for both a
monatomic and a diatomic gas, and use the values to estimate the size of the
atom and molecule. Interpret your result.
·
Try to relate to the concepts and calculations
done in Physics 213.
2. Do some research and find out more
about aerogel:
·
How is it made? What are its properties?
· What are its applications? (give a sample calculation, using the tools we learned in class; in particular, compare it [quantitatively] to more common 'insulators', like asbestos, fiberglass, etc.)
· What are the problems with widespread use?
· Try to relate to the concepts and calculations done in Physics 213.
