4 – Design an investigation to show the flow of heat from warmer to cooler objects.
3 – Describe how heat flows in predictable ways, moving from warmer objects to cooler objects until they reach the same temperature.
2 – Explain that adding heat or removing heat may result in a temperature change or change of state.
1 – Identify key terms such as heat, thermal energy, radiation, conduction, and convection.

3. How thermal energy moves

4. THERMAL ENERGY & MATTER
Thermal expansion/contraction - change in volume of a material due to temperature change.
Occurs because particles of matter collide more or less as temperature changes.

5. THERMAL ENERGY & MATTER
Specific Heat – amount of heat needed to raise ONE gram of a material ONE degree Celsius.

6. THERMAL ENERGY & MATTER
The LOWER a material’s specific heat the MORE its temperature rises when energy is added.
Which will heat faster (has the lower specific heat)?
Water? Or Lead?
Specific heat of water = 4.18 J/g°C
Specific heat of lead = 0.46J/g°C
