Problem 2.1:
3.0 moles of gas at 300 K and 1.0 atm have a volume of 15 smoots. What is
R in

?
Problem 2.2:
A sample of gas at 1.0 atm and 298 K has a volume of 8.7 L. How much gas does
the sample contain?
Problem 2.3:
You are the head engineer at a chemical plant. Sam Yagan, the summer intern,
has just broken the cooling system to the main helium tank. Sam tells you not
to be worried; the tank can withstand up to 40.0 atm of pressure before
exploding. Before Sam's accident, the tank was subjected to 10.0 atm. The tank
was originally at 250 K, but it's a hot summer day, and you fear its temperature
may rise to 350 K. Should you believe Sam?
Problem 2.4:
A race of purely gas-based aliens inhabits Jupiter (
P = 808 kPa,
T = 600 K).
On Jupiter, each alien occupies a volume of one cubic meter. The aliens decide
to visit Earth. They board their climate controlled gascraft, make the long
journey to Earth, and land in a cornfield in southern Idaho (
P = 101 kPa,
T = 300 K ). When they disembark, how big will they be? Assume that the
aliens' innards do not diffuse or burst in the Earth's atmosphere.
