A)26.3 L
B)237 L
C)0.00421 L
D)79 L
E)11.8 L

The volume of a gas is directly proportional to its temperature (in Kelvin) when the pressure and the number of moles of gas remain constant (Gay-Lussac's Law). Therefore, if the temperature is decreased by a factor of three (352 K / 3), the volume will also decrease by the same factor. The initial volume is 79.00 L, so the new volume is 79.00 L / 3 = 26.3 L.
