The temperature difference between day and night on Mars is much bigger than on Earth, due to its low atmospheric pressure. As mentioned above, the daytime temperature at the equator in summer on Mars is about 21oC. At night, it drops to about – 73oC! A syringe contains a sample of a gas with a volume of 12.0 mL during the day (21oC). What volume will the gas occupy at nighttime (– 73oC)?

A scuba diver’s tank contains 0.30 kg oxygen (O2) compressed into a volume of 2.32 L.(a) Use the ideal gas law to estimate the gas pressure     inside the tank at 5°C, and express it in atmospheres     and in pounds per square inch.(b) What volume would this oxygen occupy at 30°C and      a pressure of 0.98 atm?
