Simulation Directions
Click the "Intro" icon to begin the simulation.
Place the water and olive oil beakers on the stands by clicking and dragging them there.
Click "Link Heaters" in the upper-right blue box - this will make sure that each heat source delivers the same amount of energy per second.
Click and drag the thermometer (upper-left corner blue box) into the beaker of water and olive oil - if the left-facing arrow changes into the same color as the substance, then it is placed correctly.
- You will be timing how many seconds it takes to heat each substance to 100oC; we will perform three trials of this, averaging (mean) the time for each substance.
Use the stopwatch below the simulation to track the time. Click "start" when you begin a trial, when the first substance reaches 100oC, click "Lap" and that time will be saved as "Lap 1" but the timer will continue, when the second substance reaches 100oC click "Stop" and record each time in the data table under the stopwatch.
Each major tic-mark on the thermometer is equivalent to 50oC (see below image).
Apply heat by clicking and dragging one of the controls on one of the linked heaters to "Heat".
Record all data in the table below the simulation.
Click the reset button in the bottom-right between each trial.
Repeat the above instructions to set-up each new trial and collect the data.
When three trials have been completed and the data has been recorded, use the calculator to the right to find the mean time to reach 100oC in seconds for each substance.
