1. A quantity of gas at pressure of (50 psig) has a volume of (1000 ft'). If
the gas is compressed to (100 psig), what volume would it occupy?
Assume the barometric pressure is (14.73 psia) and the temperature of the
gas remains constant.
2. A (600 ml) sample of Nitrogen is heated from (27 °C) to (77 °C) at
constant pressure. What is the final volume?
3. A (20 L) cylinder containing (6 atm) of gas at (27 °C). What would the
pressure of the gas be if the gas was heated to (77 °C)?
4. Calculate the content of a (500 ft') tank of methane at (100 psia) and (100
°F) in: moles, pounds, molecules and SCF.
5. How many SCF of an ideal gas are required to fill a (100 ft') tank to a
pressure of (40 psig) when the temperature of the gas in the tank is (90
°F)?
6. An ideal gas exerts (100 psig) in a cylinder at (100 °F). What will the
pressure be if the temperature is reduced to (32 °F)?
7. A container was found to weight (80.0 g) while evacuated. The container
then was filled with oxygen and found to weight (81.242 g). When filled
with water the container weighed (1000.0 g). The temperature and
pressure for the procedure were (14.7 psia) and (60 oF). What is the gas
constant in engineering units?
