Chapter 13 Notes Review

What is kinetic energy?

• The energy an object has due to its motion

• The energy an object has while resting

• The energy an object has due to its kinetics

• The energy of an object

Which of the following is NOT an assumption of kinetic theory of gases?

• Particles are small with (essentially) no volume

• Particle motion is random and rapid

• All collisions are elastic

• Particles have attractive forces

Which of the following is an example of an elastic collision?

• Throwing a bouncy ball on the floor and it bounces back

• When a billiard ball hits the wall of the pool table and stops rolling

• When two cars collide in an accident and become stuck together

• Throwing a ball of clay on the floor and it flattens (doesn't rebound)

Why does a balloon filled with helium maintain its shape?

• The pressure within it

• The volume within it

• The temperature within it

• The number of particles within it

Which of the following about gas pressure is NOT true?

• Gas pressure is a force exerted by a gas per unit of surface area of an object

• Gases that exert pressure on the Earth due to gravity is called atmospheric pressure

• Gas pressure can be measured with a calorimeter

• The unit for pressure is Pascal

Which of the following is not an equivalent unit for pressure?

• 1 atm (atmospheres)

• 800 mm Hg (millimeters of mercury)

• 101.3 kPa (kilopascals)

• 101,300 Pa (pascals)

What are the conditions for STP?

• 25 C and 101.3 kPa

• 0 C and 101.3 kPa

• 250 C and 101,300 kPa

• 101.3 kPa and 760 mm Hg

Which of the following can you infer from the graph?

• The the blue peak has more energy than the red peak

• The peak of each curve is the total number of particles

• Both curves start at the origin because some molecules can have no energy

• The red curve has more molecules with more energy, towards the end of the curve

Which of the following is NOT true about temperature?

• The SI Unit is Kelvin

• Particles can never stop moving, even at very low temperatures

• Kelvin temperature is directly proportional to average kinetic energy

• Absolute zero is equal to 0 K or -273.15 degrees C
