Gas Laws Review

• Flask 1 contain the most molecules
• Flask 2 contain the most molecules
• Flask 3 contain the most molecules
• Flask 4 contain the most molecules

• Flask 1 contain the least pressure
• Flask 2 contain the least pressure
• Flask 3 contain the least pressure
• Flask 4 contain the least pressure

• Since all flask have same amount of gas, flask 1 has the least pressure
• Since all flask have same amount of gas, flask 2 has the least pressure
• Since all flask have same amount of gas, flask 3 has the least pressure
• Since all flask have same amount of gas, flask 4 has the least pressure

• Gas particles are elastic and do not attract each other.
• The kinetic energy of gas is dependent on temperature 
• Energy is not lost when gas particles collide with each other or with the walls of the container.
• All of the above

A 40.8 mol sample of methane gas, CH4 (g), is placed in a 1020 L container at 298 K. What is the pressure, in atm, of methane gas?

• 0.2 atm
• 0.4567 atm  
• 0.978 atm 
• 1.980 atm 

As the temperature increases so does the.. 

• Potential Energy

4 different flasks contain gas sample at 298 K, which of the following samples will the gas molecular be moving the slowest?  

• N2 
• O2 
• H2 
• CO2 

Convert 27 C to K

• 300
• 301
• 305
• 368

Gas pressure is caused by

• gas molecules colliding with surfaces
• gas molecules condensing to a liquid
• gas molecules hitting other gas molecule
• barometers
