 Notes: KMT, Kinetic Energy,
Intermolecular forces and phase changes
 I can describe the motion of particles in
a solid, liquid, and gas according to
kinetic molecular theory.
 I can list the six phase changes that
occur and describe them as endothermic
or exothermic.
 I can explain the significance of
absolute zero and relate Kelvin
temperature to average kinetic energy.
 Notes: Heating curves, specific heat, and
q=mcΔT
 Boil water in a paper cup
 Specific heat wksht
 Read Specific heat
of lead lab & answer
prelab questions
 I can look at a heating curve and
determine the state of matter or phase
change occurring.
 I can use the specific heat formula to
determine the energy absorbed or
released in a situation.
 Additional Practice:
q = mcΔT
 I can look at a heating curve and
determine the state of matter or phase
change occurring.
 I can use the specific heat formula to
determine the energy absorbed or
released in a situation.
 Specific heat of lead lab

predict which phase change will occur
when the temperature or pressure
changes.

present at a given temperature and
pressure.

Having studied this chapter and done the problems, the student should be able to:
1. Describe the motion of particles of a solid, liquid, and gas according to the kinetic theory.
2. Distinguish between contained gases and uncontained gases.
3. Relate temperature to the average kinetic energy of the particles in a substance.
4. Explain the significance of absolute zero, giving its value in degrees Celsius and Kelvin.
5. Use the kinetic theory to explain gas pressure.
6. Convert between the units of pressure of Pa, atm, and mm Hg.
7. State the values of standard temperature and pressure (STP).
8. Describe the nature of a liquid in terms of the attractive forces (intermolecular forces) between its particles.
9. Explain why a liquid has a vapor pressure, and why a change in temperature causes a change in vapor pressure.
10. Name six possible phase changes that matter can undergo, and describe them as exothermic or endothermic.
11. Be able to identify the type(s) of intermolecular forces present in a substance.
12. Given a number of substances, be able to predict which substances would have the highest boiling point, and why.
13. Given a phase diagram, tell whether the substance would be a solid, liquid, or gas at a given temperature.
14. Calculate the energy change associated with a phase and temperature change. (calories problems)
