The figure shows a pV diagram
for 2.5 g of oxygen gas (O2) in a sealed
container. The
temperature T 1 of the gas in
state 1 is 18°C. What are the
temperatures T 3 and T 4 of
the gas in states 3 and 4? The ideal gas constant
is R = 8.314 J/mol · K = 0.0821 L · atm/mol · K,
and the ATOMIC weight of oxygen is 16 g/mol.
a) 14°C, 41°C
b) 9.0°C, 27°C
c) -55°C, 380°C
d) 220°C, 650°C
