1. Heat
ICP Chapter 11

2. Heat/Temp/Energy Heat – flow of thermal energy
Heat flows from the warmer object (higher energy) to the cooler one (lower energy)
Temperature – average kinetic energy per molecule from random motion
Thermal Energy – energy of moving/vibrating molecules – energy related to temperature

4. Units
Heat is energy – it can be measured in Joules (like KE, PE, and work), calories, or BTU (British Thermal Units).
1 calorie = joules
1 BTU = 1055 joules

5. Conductors, Insulators
Conductor – transfer or move heat energy
Insulator – Keeps the heat energy inside – keeps it from leaving

6. Specific Heat
The temperature increase of an object depends on its mass and the material from which it is made.
Specific heat is a property of a material telling us how much heat energy is needed to raise the temperature of 1 kg by 1°C.

7. Specific Heat
Knowing the Specific Heat (or Cp) value tells you how fast the temperature of something will change as it gains or loses energy.
Metals will warm up (or cool down) fast
Styrofoam will take a longer time and more energy to change temperature.
Many mugs are made from ceramics. Will those have a larger or smaller specific heat than iron?
Why do pots have plastic handles?
Would you rather stir boiling water with a metal or a wood spoon?

8. Specific Heat Equation
E = mCp(T2-T1)
E  Heat Energy (J)
M  mass (kg)
Cp  Specific Heat (J/kgC)
(T2-T1 )  change in temp (°C)
