Honors Calorimetry Activity
In this activity , you will plan and conduct an investigation
on energy transfers between
two liquids of different temperatures.
Objective:
Plan and then conduct an investigation
on energy transfer between two
liquids of dif ferent temperatures.
Materials:
thermometer , two foam cups, measuring cup
from your kitchen, hot water ,
and one liquid selected from the chart below and placed
in your refrigerator for one or
more hours before you begin your activity

Caution
: You will be working with hot water in this
lab. Be very careful as you pour so you do
not burn yourself. Also, be sure to read your thermometer
carefully. The numbers on the
thermometer scale refer to the line under the number.
Lastly, it's important to perform certain
steps quickly and efficiently to minimize heat loss
to the surroundings.

Read the entire procedure before you begin the experiment.
2.
Use the metric scale on your measuring cup to measure
237 mL (1 cup) of your
selected refrigerated liquid. Pour this liquid into
one of the foam cups.
3.
Now, get the hottest water possible from the faucet
on your sink. Use the metric
scale on your measuring cup to measure 237 mL (1 cup)
of hot water . Pour this
water into the other foam cup.
4.
Quickly measure the temperature of the cold liquid
and the hot water . Record the
temperatures in a data table.
5.
Very quickly pour the hot water into the cold liquid.
Place the thermometer in the
mixture. Invert the cup that contains the cold liquid
over the cup containing the
water mixture.
6.
Keeping the bulb of the thermometer in the liquid,
check the temperature reading
about every 20 seconds until the temperature stabilizes.
Keep the lid (inverted
cup) in place as much as possible. When the temperature
is constant (this will
happen very quickly), record this temperature in a
data table as the final
temperature.
Data:
Create a data table for your measurements and calculations.
Two measurements are
provided for you. Record the other measurements needed
for this activity .
