In the Question: A cylinder has a volume of 5.4 L of air at a pressure of 140 atm. If the volume is increased to 12.4L, what would the new pressure be? Which answer choice has the data correctly labeled?

• P₁=5.4L, V₁=140atm; P₂= 12.4L, V₂= ?

• P₁=140atm, V₁=5.4L ; P₂= ?, V₂=12.4L

• T₁=140atm, V₁=5.4L ; T₂= ?, V₂=12.4L

• There was no important data to label

Which container will have a lower pressure? Assume that the temperature did not change.

• left
• right
• they both have the same pressure
• I don't know

If I initially have 4.0 L of a gas at a pressure of 1.1 atm, what will the volume be if I increase the pressure to 3.4 atm?

• 1.29 L

• 12.36 L

• 1.29 atm

The oxygen tanks on the sideline can be very dangerous if heated. Suppose an oxygen tank has a pressure of 120 atm at a room temperature of 25°C. If the temperature on the turf or field increases to 51°C, what will the resulting pressure of the oxygen tank be if the volume and amount of gas does not change?

• 130 atm
• 804 atm
• 1.30 atm
• 254 atm

Waiting to play the Broncos, the Patriots notice the change in the barometric pressure that occurs when arriving in Denver, CO. In Boston, if the temperature is 25°C at a barometric pressure of 101.3 kPa, what would the temperature of the air be if the barometric pressure decreased to that of Denver’s; 84.0 kPa?
