The graph of a Direct relationship will look like?

•

The graph of a Indirect (Inverse) relationship will look like?

At a constant Temperature, which line best shows the relationship between the volume of an ideal gas and its pressure?

• 
• 
• 
• 

If the pressure on a given gas in a closed system is increased and the temperature remains constant, the volume of the gas will:

• increase

• decrease

• stay the same

If a balloon is heated, what happens to the pressure of the air inside the balloon if the volume remains constant?

• I can't predict that!

• Off course it stays the same :)

• It increases

• it decreases

Avogadro's law states that equal volumes of different gases would have:

• same number of molecules

• different number of molecules

Which of these balloons will have 4 moles of gas?

• Hydrogen

• Nitrogen

• Oxygen

According to Avogadro's law, since all 3 of these balloons are the same volume (size) they must have:

• Different amounts of each type of gas

• The same amount of gas inside

A 1 liter flask of CO₂ and a 1 liter flask of H₂ are both at the same temperature and pressure. The ratio of the number of molecules of CO₂ to the number of molecules of H₂ in the flask is?

• 1:1

• 2:3

• 3:2

• 1:3
