**Problem : **
Molly admires her red balloon, which has a volume of 2.0 liters at sea level
(1.0 atm). A clown catches her eye, and she lets go of the balloon. The red
balloon goes up and up until the pressure around it is 0.80 atm. Assuming
isothermal conditions, what is the new volume of Molly's red balloon?

**Problem : **
Graph the pressure vs. volume relationship dictated by Boyle's law. If Boyle's
law stated that
*P* = *aV*
, where
*a* < 0
, what would the graph of
*P*
vs.
*V*
look like?

**Problem : **
Initially the volume and pressure of a sample of gas are 1 dm
^{3}
and 10 smoots,
respectively. The volume is raised isothermally to 10 dm
^{3}
. What is the
pressure of the gas in smoots under these conditions?

**Problem : **
One end of a mercury filled manometer is open to the atmosphere, while the
other is closed and contains a vacuum. What does the height difference
*h*
of
the Hg columns measure?

**Problem : **
The pressure of gas A (
*P*
_{A}
) is 3.0 atm. The height of the mercury column
*h*
is 1140 mm. What is the pressure of gas B (
*P*
_{B}
) in atmospheres? Assume that
1 mm Hg = 1/760 atm.
