Energy Test Review
Heat Versus Temperature
What is the difference?
Heat and temperature are not the same thing.
Heat
Heat is the transfer of thermal energy between
substances of different temperature.
As thermal energy is added, the temperature of a
substance increases.
Temperature
Temperature is a measure of the average kinetic
energy of the molecules of a substance.
Increased temperature means greater average
kinetic energy of the molecules in the substance
being measured, and most substances expand when
heated.
The temperature of absolute zero (–273oC/0 K) is the
theoretical point at which molecular motion stops.
Thermal Energy Exchange
How do molecules act as we add heat?
Observe phase changes simulation (PhET)
Thermal Energy Exchange
As thermal energy is added to or taken away from a
system, the temperature does not always change.
There is no change in temperature during a phase
change (freezing, melting, condensing, evaporating,
boiling, and vaporizing) as this energy is being used
to make or break bonds between molecules.
So what does the line graph of a phase change look
like?

Complete the practice sheet
Heat and smell
Raise your hand once you smell the spray.
How did the smell travel through the air?
Would the temperature of the room affect how
fast the smell travels?
Think about a time them smelled a bad odor coming
from a garbage can. Would this scent be more potent
in the winter or on a hot summer day? Why?
Heat and Diffusion
Record the temperature of each beaker of water
Predict which sample they think food coloring will
diffuse through fastest. Predictions must include an
explanation!
Observe the movement of the food coloring in each
beaker.
Which sample of water allowed the food coloring to
diffuse (spread out) faster?
Why did this happen?
Vocabulary Sort
