P8 G.T. Energy Transfer in Different Types of Matter (1)

Energy Transfer in Different Types of Matter
Temperature and Energy​.
In this simulation you will be able to see the relationship between energy a
​ nd temperature and
show in both words and pictures how energy is transferred between two objects at different
temperatures. ​Be sure to click the “Energy Symbols” box so the
different types of energy will be visible throughout your
investigative process.
Learning Objective:
Predict how energy will flow when objects are heated or cooled, or for objects in contact
that have different temperatures.
The PhET Simulation: Energy Forms and Changes
available at:​ ​https://phet.colorado.edu/en/simulation/energy-forms-and-changes
Getting Familiar With The Options- Go to the Intro Tab
1. 1) Mess about with moving the objects around. Heat them, cool them, watch the energy
flow. You can put the objects in many different configurations try them out.
a. Is it possible to boil the water? Is it possible to freeze the water? (Make sure to
attach the temperature gauge so you have a guide.) What do you need to do to make
these changes?
Yes, and yes. You either need to heat or freeze.
b. Chill the water as much as possible – then add heat and observe. List at least three
things you noticed.
It defrosts quickly, there is more heat molecules, and the temperature rises
2. In the boxes below, (a) draw the model given in the simulation and then (b) draw a model of
the molecules in an object when
3. the object is cold (left) and when the object is hot (right). Assume that the object in both
pictures is the same object (iron, brick, or water) just at different temperatures.
(a) ​Cold Object Energy Model from sim​ulation
(a) ​Hot Object Energy Model from simulation
(b)​ Cold Object Molecules
(b) ​Hot Object Molecules​
4. Heat up the brick and the iron to the same temperature. Draw the differences do you
a. Which one can hold more energy?
b. How and where so they lose their energy?
They lose the energy by cooling down. The energy goes in the air.
4. Place the brick on top of the iron and add heat. Draw and describe what happens.
The iron is keeping all the heat and rarely heats the brick.
5. Take the same set up from #5, instead of heating it up, cool it down. Draw and describe
what happens.
The brick is now holding all the heat.
6. Once the brick and the iron are cooled down, do they have the same thermal energy? Do they
have the same temperature? Does the room temperature water have more or less thermal
No and no, and water has more thermal energy.
7. What material can hold the most heat? Which take the longest to cool down? (Is it the same
First, water can hold the most heat. THE longest to cool down is the brick.
8. ​Put a hot object into cold water. Draw what happens to the energy in each of the stages.
The hot, thermal energy is release into water. This is because it cools
down with the cold water. There is apparently more water.
9. When and why does the process in #8 stop?
When all the extra hot thermal energy is released in water, besides what iron had for
base temperature.
10. ​Plan an investigation in the real world to collect data to test the model from 10 and 11.
What is your question?
Can you extinguish a burning stick by dumping it in the cold, pacific
What ​variable will you
The iron cube
What variable will you
How fast the hot, thermal energy cools in seconds.
What will be held
The speed of throwing a stick
What is the procedure
for the experiment?
Somehow put a thermometer and a way to locate it on a burning
● Throw it into the Pacific Ocean.
● Count how long in seconds it takes to cool the stick down.
● Rescue the log.
13). What does temperature measure? Support your answer with evidence from the
simulation​. If you need to do some reading on this before you answer the question, here

Temperature measures the heat of molecules on a thing.
