1. These railroad tracks all buckled due to thermal expansion during an extremely hot day!

2. Structures are inherently weak at these expansion joints

3. This Oakland / SF bay bridge section failed during the 1989 Loma Prieta earthquake

4. The Unusual Behavior of Water
 As the temperature of water decreases below 4oC, the volume of water increases so the density of water decreases.

6. Heat conduction
Men replacing damaged heat-shielding glass ceramic tiles on space shuttle Columbia, after its thirteenth mission.

8. Convection
 Because of convection, hot air rises and creates updrafts or thermals:

9. Examples of Convection Currents

12. Radiation
Radiation is a heat transfer mechanism that utilizes electromagnetic waves to carry energy away from the emitting object.
Radiated power is given by the Stefan-Boltzmann law:
