Question

5. One mole of oxygen gas is at a pressure of 6.90 atm and a temperature of 25.0°C.

(a) If the gas is heated at constant volume until the pressure
triples, what is the final temperature?

°C

(b) If the gas is heated so that both the pressure and volume are
doubled, what is the final temperature?

°C

6. (a) An ideal gas occupies a volume of 1.6 cm^{3} at
20°C and atmospheric pressure. Determine the number of molecules of
gas in the container.

(b) If the pressure of the 1.6-cm^{3} volume is reduced to
2.4 ✕ 10^{−11} Pa (an extremely good vacuum) while the
temperature remains constant, how many moles of gas remain in the
container?
