In this chapter we will explore the following topics:
Temperature and the Zeroth law of thermodynamics Thermometers and temperature scales Thermal expansion Temperature and heat Specific heat Heats of transformation Heat, work, and the first law of thermodynamics Heat transfer mechanisms

2. Temperature

3. The Zeroth Law of Thermodynamics
Thermoscope
If body A is in thermal equilibrium with body T and body B is in thermal equilibrium with body T, then A and B are in thermal equilibrium with each other.

4. The Triple Point of Water
