Consider the low-speed flight of a Space Shuttle as it is nearing a landing. If the air pressure and temperature at the nose of the shuttle are 1.00 atm and 300 K,
respectively, calculate the density and specific volume.
The density is 1.17 ± 2% kg/m3.
The specific volume is 0.85 ± 5% m3/kg.
Explanation:
SC
ρ = P/RT = (1.00 × 1.01 × 105)/(287 × 300) = 1.17 kg/m3
ν = 1/ρ = 1/1.17 = 0.85 m3/kg
The density is 1.17 kg/m3.
The specific volume is 0.85 m3/kg.

Consider 1 kg of helium at 500 K. Assuming that the total internal energy of helium is due to the mean kinetic energy of each atom summed over all the atoms,
calculate the internal energy of this gas. Note: The molecular weight of helium is 4.
The internal energy of the gas is 1.558 ± 2% × 106 J.
Explanation:
3 3
Mean kinetic energy of each atom = 2 kT = 2 (1.38 × 10 − 23) (500) =1.035 × 10 − 20 JOne kg -mole, which has a mass of 4 kg, has 6.02 × 10 26 atoms.Hence 1 kg
U
The internal energy of the gas is 1.558 × 106 J.
