A diatomic ideal gas is confined to a closed container of volume
0.1 m^3. (Assume that the volume remains
constant.) Initially, the pressure of the gas is 2 atm and its
temperature is 300 K. Assume that both the
translational and the rotational degrees of freedom are
active).
1- If the internal energy of the gas is doubled, which one of
the following is true?
a. The pressure increase by a factor of .sqrt(2)
b. The ratio between the kinetic and rotational energies
increases.
c. The density increases.
d. The pressure increases by a factor of 2.
e. The pressure does not change.
2- Which of the following answers best approximates the amount
of heat that is required to raise the
temperature of this gas by 4 K?
a. 50625 J
b. 675 J
c. 0 J
d. 405 J
e. 270 J
