Energy Transfer - Calorimeter
Included components
1
ET-8499
Outer cup
Holds the inner cup and acts as an insulator. The mass of this cup
does not need to be included in any calculations.
2
3
Inner cup
1. Place the spacer onto the lip inside the outer cup.
Insulating lid
2. Place the inner cup into the outer cup through the hole in the
spacer.
Insulating spacer
Aligns the inner and outer cup to create a small air space between
the cups, which acts as an insulator. The spacer rests on the step
inside the outer cup.
5
Heating resistor assembly
Heats the water in the inner cup when powered. Permanently
mounted in a two-hole stopper, with the second hole providing
access for a temperature probe, such as the Wireless Temperature
Sensor (PS-3201).
6
CAUTION: Do NOT touch the resistor during or shortly after it
is used for heating! Doing so may cause burns.
Holds the water and investigation samples. This cup's mass
should be included in heat transfer equations. Made of aluminum.
Features a hole for the heating resistor assembly or the one-hole
stopper.

Equipment setup
One-hole stopper, #2 (not shown)
Insert into the insulating lid for experiments where you are not
using the heating resistor assembly. Use the hole to insert a
temperature probe or thermometer.
3. Fill the inner cup with water and a sample for your experiment,
then place the lid on top of the inner cup.
4. Insert the heating resistor assembly through the hole in the lid,
making sure the stopper fits snugly. (If the heating resistor is
not being used in your experiment, insert the one-hole stopper
instead.)
5. Connect the heating resistor assembly to a power supply.
IMPORTANT: To avoid damaging the product, only
apply power to the resistor when it is immersed in water,
and do not apply more than 10 V to the resistor at any
time.
6. Insert a temperature probe or thermometer into the empty hole in
the stopper.
Storage
Before storing the apparatus, remove all water and other components
from the inner cup. In particular, make sure to remove the heating
resistor assembly from the hole in the lid. Storing the product with
the resistor assembly inside the cup will seal in any residual moisture,
potentially corroding the resistor over time.
