Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical
forces between particles. [Clarification Statement: Emphasis is on understanding the strengths of forces between particles, not on naming specific
intermolecular forces (such as dipole-dipole). Examples of particles could include ions, atoms, molecules, and networked materials (such as graphite).
Examples of bulk properties of substances could include the melting point and boiling point, vapor pressure, and surface tension.] [Assessment Boundary:
Assessment does not include Raoult’s law calculations of vapor pressure.]

Essential Questions
Enduring Understandings
How is matter held together?
That all matter is held together by by
electrical forces between molecules?
Labs, Investigation, and Student Experiences
Modifications (ELLs, Special Education, Gifted and Talented)
Bulk properties are due to inter and
intra molecular forces? These
properties can be BP or MP.
· Teacher tutoring
· Peer tutoring
Understand that different bonds form
different results of the bulk property of matter
such as BP and MP.
· Cooperative learning groups
· Modified assignments
· Differentiated instruction
Understand why water has such different
properties from similar compounds?
Content Statements
Cumulative Progress Indicators
Gas particles move independently
and are far apart relative to each
other. The behavior of gases can be
explained by the kinetic molecular
theory. The kinetic molecular theory
can be used to explain the
relationship between pressure and
volume, volume and temperature,
pressure and temperature, and the
number of particles in a gas sample.
There is a natural tendency for a
system to move in the direction of
disorder or entropy.
Use the kinetic molecular theory to describe
and explain the properties of solids, liquids,
and gases.

Instructional Guidance for

●
Describe the nature of gases and recognize that gases have mass, can be
compressed, exert pressure, occupy space available to them and diffuse rapidly.
State the six postulates of the kinetic-molecular theory and explain how they
account for the physical properties of gases.
Explain how the four gas variables – amount, temperature, volume and pressure
are expressed.

Heating increases the energy of the
atoms composing elements and the
molecules or ions composing
compounds. As the kinetic energy of
the atoms, molecules, or ions
increases, the temperature of the
matter increases. Heating a pure
solid increases the vibrational energy
of its atoms, molecules, or ions.
When the vibrational energy of the
molecules of a pure substance
becomes great enough, the solid
melts.

Sample Assessments
To show evidence of meeting this CPI, students may answer the following questions:
1. Suppose that you drop a 50.0 g piece of metal, at 100.0 oC, into an insulated vessel
containing 100.0 mL (density = 1.0 g/mL) of water at 25.0 oC. What is the specific
heat of the metal if the final temperature of the combined metal/water system is 30.0
oC?
The specific heat of water is 4.184 J/(g oC).
2. The enthalpy change for the following reaction is
∆Ho = 543 kJ.
2 POCl3(g) →> 2 PCl3(g) + O2(g)
Is this reaction endothermic or exothermic? Explain why.
3) Give an example of a physical change that is endothermic, and an example of a
physical change that is exothermic.
