In this lab, you will investigate how heat is transferred from one material to another.
Procedure
Part 1: Heat Transfer from Liquid to Liquid
1. Set up the computer to measure the real-time temperature from the two temperature probes.
2. Measure 150 mL of hot water (as hot as a standard faucet provides, or cold water heated to
approximately 65°C using a hot plate or a ring stand/ring screen over a burner) in one beaker and
150 mL of cold water (as cold as a standard faucet provides) in another beaker. Place a
temperature probe and a Celsius thermometer in each beaker. Wait 30 seconds, and confirm that
the temperature measured by each probe matches the temperature on the Celsius thermometer in
the same beaker. Record the temperatures in data table 1. (Note: All temperatures in this lab
should be recorded in Celsius.)
3. While you are waiting for the temperature probes to read a final, stable temperature, calculate
the expected final temperature of the mixture of hot and cold water. Use the equation Q =
mcΔT and the fact that Qlost + Qgained = 0. (The specific heat capacity (c) of water is 4.18 J/g·°C.)
Record your prediction in data table 1.
4. Pour the hot and cold water into the calorimeter. Use one of the temperature probes to slowly
stir the mixture of water for about 1 minute. Record the final temperature of the mixture in data
table 1.
5. Discard the water in the calorimeter.
