## The PhET simulation Energy

Introduction:
You will use the PhET simulation Energy forms and changes to predict, experiment, discover and interpret the me
Warm-Up:
Describe what the following terms mean
Temperature –
Heat –
Using your definition for temperature above, explain how a thermometer works to provide a visual representation
Thermometers in the past were filled with mercury but most are now filled with alcohol instead due to safety reaso
The simulator allows you to add the same amount of heat energy to different materials e.g. water, oil, iron, brick. I
you predict that each will have the same temperature changes? Explain.
Experiment:
Position the Iron block on one of the ring stands and move a thermometer to the block to measure the temperatur
Describe what you observe.
Predict what you would see if you are able to measure the temperature of the Iron block and Brick block as you s
Click the reset button, then drag the iron block on one stand and the brick block on the second stand. Again, put a
and Link Heaters tabs. Before adding any heat to the blocks, observe any differences in the blocks and provide a
Observation & Analysis:
Increase the temperature on the blocks and observe the thermometers and record observations
If you wanted to use these experiment to get quantitative observations and create a graph showing trends, list the
Independent –
Dependent –
Control –
Repeat the comparison done with the blocks above, this time comparing the two liquids. Record your observation
Repeat again this time comparing water and iron. Records your results.
Discussion:
Specific Heat Capacity is the amount of heat energy required to raise the temperature of a substance per unit of m
Different materials have different specific heat capacities.
Your task here is to determine the relative specific heat capacities of four materials: brick, iron, olive oil and water
We’re trying to place the objects in the correct order, from lowest to highest values of c. You will be using a series
Before you begin, read through the directions and create a suitable data table to record your results.
Click the “Intro” icon to start the simulation.
Click the “Link Heaters” box in the top-right part of the screen. This will ensure the two heaters give out the same
Place two different materials on the stands by clicking and dragging them there.
Click and drag a thermometer from the top-left corner of the screen onto each material. The thermometer is corre
Click and hold one of the heater temperature controls, then drag it up towards “Heat” and hold it there. You should
cool down; if you need to heat them up again, just click, drag and hold the slider back up again.
When you’re done, click the orange Reset button in the bottom-right corner of the screen. You will have to re-chec
Go through all the possible combinations of materials, compare results, and rank them from lowest to highest valu
Order the materials from smaller to larger specific heat capacity.
