In outer space the density of matter is extremely low, about one atom per cm3. The matter is mainly hydrogen atoms (m = 1.67 × 10-27 kg) whose rms speed is 260 m/s. A cubical box, 1.70 m on a side, is placed in outer space, and the hydrogen atoms are allowed to enter. (a) What is the magnitude of the force that the atoms exert on one wall of the box? (b) Determine the pressure that the atoms exert. (c) What is the temperature of outer space?

Which of the following statements about batteries is false?
Lithium–iodine batteries have low current, but extremely long life.
Lead storage batteries contain lead at the anode and lead coated
with lead dioxide at the cathode. It is not safe to recharge a
nickel–cadmium battery. A fuel cell is a galvanic cell for which
the reactants are continuously supplied. Dry cell batteries are
used in flashlights and portable radios.

(a) One of the first "pure" Bose Einstein condensates was
created with a low density (1020 molecules per cubic
meter) gas of lithium with an atomic mass of 7.02 u. What is the
critical temperature for the transition to a Bose Einstein
condensate for lithium? Assume the spin for the atom is 1. The
temperatures actually achieved in these experiments were below 100
nK. What fraction of the lithium molecules are in the Bose Einstein
Condensate phase at 100 nK?...

A space station is about to disintegrate. There is room for one
person in an escape pod which will preserve that person’s life
until a rescue vehicle can arrive. There are three persons left on
the station: a 20 year old student (that is you), a 50 year old
scientist and a young child. Who should be given the space in the
escape pod, or should the three draw lots and decide randomly?

The density of gasoline is about 6 pounds per gallon, and carbon
accounts for nearly all the weight of gasoline Show that combustion
of 1 gallon of gasoline produces about 20 pounds of CO2
(the exact value is closer to 22 pounds)
