Find the Lab
∎ In your web browser, go to www.gigaphysics.com, then click Virtual Labs, and finally
Mechanical Equivalent of Heat.
∎ If someone else used the computer for this lab before you, click Reset Experiment. This will
ensure that you have your own unique data when you do the experiment.
Part I: Proof of Concept
∎ Use the Choose a metal menu to select copper.
∎ one of the measurements you will need throughout this lab is the distance the
shot will fall. To find this distance, use your mouse to drag the ruler next to the
tube. Measure from the top of the tube to the top of the copper shot. Record this
length in the table below.
∎ You will also need the mass of the shot. Click Open Tube, then drag the shot
to the electronic balance. The balance will display the mass in grams.
∎ Convert this mass to the SI unit of kilograms, and record it in the data table. ∎
you’ll need the shot’s initial temperature as well, so drag the shot onto the red
laser dot in front of the infrared thermometer (it’s under the balance). The
thermometer will display the temperature in °C; add this to the data table as
