KMT and Gas Behavior

Which phrase describes the motion and attractive forces of ideal gas particles?

• random curved-line motion and no attractive forces

• random straight-line motion and strong attractive forces

• random straight-line motion and no attractive forces

• random curved-line motion and strong attractive forces

A cylinder with a tightly fitted piston is shown in the diagram above. As the piston moves downward, the number of molecules of air in the cylinder

• decreases

• increases 

• remains the same

"STP" in chemistry is the abbreviation for:

• Stone Temple Pilots

• Standard Temperature and Pressure

• Scientifically Treated Petroleum

• Space Test Program

"STP" is equal to the following:

• 273 K, 1 atm

• 22 K, 1 atm

• 0 K, 273 atm

• 273 C, 760 mmHg

Which has more particles?

• 10 moles of N2 gas in a 2 L balloon

• 10 moles of N2 gas in a 7 L balloon

• They have the same amount of particles

• Moles are animals, not particles

Which has more particles?

• 2 mol of H2 gas in a 10 L balloon

• 7 mol of H2 gas in a 10 L balloon

• They both have the same

• moles are slightly raised blemishes on your skin

Pressure is caused by:

• Gas molecules colliding with surfaces

• Gas molecules reacting with each other

• Gas molecules colliding with each other

• Gravity

As the temperature of a gas increases with the volume remaining constant, the pressure of the gas

• decreases

• increases

• remains the same

Which state of matter has the most space between molecules?

• Solid

• Liquid

• Gas

• All of the above

At STP, how much volume does one mole of any gas occupy?

• 22.4 L

• 6.02*10^23

• 32.5 L

• It depends on the gas.
