Calorimetry
Contributors
Summary
Three “coffee-cup” calorimetry experiments:
1) Use of the Law of Dulong and Petit to identify an unknown metal
2) Measurement of the enthalpy of sublimation of dry ice
3) Exploration of the relationship between surface area and the rate of heat transfer and the amount of heat transferred
Featuring contributions from Tamara Fitzjarrald

Chemicals and their CAS numbers.
Aluminum 7429-90-5
Iron 7439-89-6
Nickel 7758-02-0
Tin 7440-31-5
Dry ice (carbon dioxide) 124-38-9
Soda-Lime Glass 2446523-50-6
Precautions, including proper personal protective equipment such as goggles and gloves, should be used when working with experiments. There is always a chance glass could break from thermal shock. Always wash your hands after completing the experiments and demonstrations. DO NOT discard the metallic or glass solids; they can be reused.
