Chemistry through Inquiry Teacher Guide

(PS-2871C)

Features over 25 inquiry based labs covering the fundamental concepts of lab skills, structure & properties of matter, chemical reactions and more.

Specific Heat

Lab Summary

Use a fast response temperature sensor to determine the identity of an unknown metal by calculating the specific heat of the metal and comparing it to a list of known values.

Theory

Experimentally determine the identity of an unknown metal. Through this investigation, students:

  • Differentiate the concepts of temperature and heat.
  • Understand the fundamental components of specific heat.

Method

Students conduct the following procedures:

  • Record physical observations of the unknown substance.
  • Use a calorimeter to measure the temperature change inside.
  • Calculate specific heat of an unknown metal.
  • Identify the metal from a list of options.
