The temperature ot 2.5 L of a gas initially at SUN
increased to 2507”C at constant volume. Calculate the
final pressure of the gas in atm.
The pressure of 6.0 L of an ideal gas in aflexible
contalner 1S decreased to one-third of its original
presSure, and 1ts absolute temperature 1s decreased
by one-half. What 1s the flnal volume of the gas?
A gas evolved during the tfermentation of glucose
(wine making) has a volume of 0.78 L when mea-
sured at 20.1?C and 1.00 atm. What was the volume
of this gas at the fermentation temperature of 36.5 C
and 1.00 atm presSure?
