Gas Law Notes

Open Ended

What is pressure? And how can you change the amount of pressure on something?

Open Ended

If you had a syringe, what would happen to the pressure inside the syringe as you push down (decrease volume)?

Open Ended

What are the names of the three laws we've learned so far?

Open Ended

If the Kelvin temperature of a gas sample held in a steel tank increases to three times its original value, predict what will happen to the pressure of the gas. Will it increase or decrease? By what factor do you expect the gas pressure to change?

Open Ended

A gas sample at a constant pressure shrinks to one-fourth its initial volume. What must have happened to its temperature? Did it increase or decrease? By what factor did the Kelvin temperature of the gas change?

Explain why automobile owners in severe northern climates often add air to their tires in the wintertime and release some air from the same tires in the summertime.

Open Ended

Use kinetic molecular theory and gas laws to explain why a weather balloon expands in size as it rises from Earth’s surface.

Open Ended

A 0.50-L canister of hazardous sarin gas was discovered at an old, abandoned military installation. To properly dispose of this gas, technicians must know how much gas is held in the canister. The gas pressure is measured as 10.0 atm at room temperature (25°C). How many moles of sarin are held inside?

Open Ended

What volume will 2.0 mol H2 occupy at 40.0°C and 0.50 atm pressure?

Open Ended

How many moles of gas do I have if I have a gas in a container with a volume of 4L at STP?
