RQzz - KMT & GAS LAWS

What is one assumption that must be made for the kinetic molecular theory to be applied to gases?

• Collisions between gas particles are inelastic.

• Gases consist of closely spaced particles.

• Gas particles move in constant straight line motion.

• Each gas particle has a definite volume.

Under what temperature and pressure conditions does a gas behave the most like and ideal gas? (Choose all that apply.)

• high pressure (above 1 atm)

• low temperature (below 273 K)

• standard temperature

  (273 K)

• standard pressure (1 atm)

The pressure exerted by a gas does not depend on

• temperature.

• volume.

• number of moles present.

• the identity of the gas.

Of these three states of matter, which one has the most kinetic energy? 

• Solid 
• Liquid 
• Gas

What is one assumption that must be made for the kinetic molecular theory to be applied to gases?

• Collisions between gas particles are elastic.

• Gases consist of closely spaced particles.

• Gas particles rarely move.

• Each gas particle has a definite volume.

Under what temperature and pressure conditions does a gas deviate from the ideal behavior? (Choose all that apply.)

• higher pressure (above 1 atm)

• lower temperature (below 273 K)

• standard temperature

  (273 K)

• standard pressure (1 atm)

• Volume increases, temperature decreases.

• Volume increases, temperature increases.

• Volume decreases, temperature increases.

• Temperature increases, volume decreases.

If a balloon has a volume of 1.0 L at 0⁰ C, which of the following locations would cause the balloon to increase in size?

• Long Beach, CA where the temperature is about 38⁰ C.

• Mt. Everest where the temperature is about -27⁰ C.

What units must temperature always be in for ALL the gas laws?

• Celcius

• Kelvin

• Fahrenheit

• Kelvin or Celcius

If you place a balloon in a freezer what happens to the size of the balloon?

• Doubles
• increases
• decreases
• stays still
