Behavior of Gasses and Gas Laws

Which is a property that only gasses display?

• Particles are spread out to fill all available space
• Take the shape of their container
• Can't be compressed
• All of these

Pressure, volume, moles and height are the four important variables when studying the behavior of gases.

• TRUE
• FALSE

Pressure and volume have an inverse relationship.  When pressure increases, volume will...

• stay the same
• increase
• decrease
• I don't know

You have a gas that has a pressure of 2 atm and a volume of 10 L.  What would be the new volume if the pressure was changed to 4 atm?

• 5 L
• 20 L
• It would stay at 10L
• 1 L

Directly proportional means that as one value increases ....................

• the other stays the same 
• the other increases as well
• the other decereases
• the other goes to zero

Inversely proportional means as one value increases the other............. 

• increases 
• decreases 
• stays the same 
• goes to zero

Which equation will help determine the number of moles in a container of gas at STP with a volume of 99.2 L.

• $\frac{V_1}{n_1}=\frac{V_2}{n_2}$

• PV = nRT

• $\frac{P_1}{T_1}=\frac{P_2}{T_2}$

• $\frac{V_1}{T_1}=\frac{V_2}{T_2}$

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

• 12.36 atm

What is STP?

• 1 Degrees Celsius and 0 ATM

• 0 Degrees Celsius and 1 ATM

• 0 Kevin and 10 ATM

• 273 Celsius and 273 ATM

Adding heat to a non-flexible container of gas will cause

• the molecules to slow and down hit the sides less often. The pressure will decrease.

• the container to explode.

• the molecules to speed up and hit the sides more often. The pressure will increase.
