Lab: Calorimetry
In this lab, we’ll use an online simulation of calorimetry, the measurement of heat
transfer, to predict the final temperature when a heated sample of known
material is placed in water and allowed to equilibrate, and identify an unknown
material based on calculating its specific heat.
Part I: Predicting Final Temperature When Cooling a Known Sample
1. Consider the following situation. A 50-g block of iron is placed in a
beaker of water, which is then brought to a boil using a hot plate. The
iron is then placed in 200-g of water which is at room temperature
(20C). If no heat is lost to the surroundings, what should the final
temperature of the iron and water be after reaching thermal equilibrium?
Show all work below.

2. Now let’s test our calculations in a simulation! Go to the following
website:

3. Click the “Experiment” tab, then click the button: “Run Experiment”
4. We’ll be heating a solid, so click the “Solids’ tab and then choose Iron.
5. Set the mass of the iron to be 50 g, and set its temperature to be 100C.
6. Click “Next”.
7. Choose Water as your liquid. Set its mass to 200 g and temperature to
20C.
8. Under “Run Experiment” select the box for “Show Graph View”. Then
click “START”.
9. What is the final temperature of the iron and water after thermal
equilibrium is reached?
