1. Conductors, Insulators, Specific Heat, & Thermal Expansion
Definitions for Notebook

2. Copy These Definitions in Notebook: (Entry 40)
Conductor – A material that allows heat to
transfer through it easily
Example: Metals
2. Insulator – A material that does not allow heat
to transfer through it easily
Example: Styrofoam or Wool

3. Specific Heat:
When an object is heated, its temperature will rise.
Temperatures do not increase at the same rate for all objects
Some objects require more Heat Energy to raise the temperature by the same amount.
The amount of energy required to raise the temperature of 1kg of a material by 1 Kelvin is called specific heat.
Ex: Sand and Water

4. Thermal Expansion:
the tendency of matter to change in volume in response to a change in temperature.
When heated, the particles of matter speed up. As they speed up, the particles spread out. The expanding of matter when it is heated is called Thermal Expansion
