5. What is Temperature? English System: Fahrenheit (°F) .
(boiling point of water = 212°F)
(freezing point of water = 32°F)
Metric System: Celsius (°C) .
(boiling point of water = 100°C)
(freezing point of water = 0°C)
temperature - a measurement of the amount of energy/motion present in an atom or molecule
Absolute Zero
-460°F

6. Three Ways Heat is Transferred
Conduction –
heat is transferred through the collision of atoms
Convection –
heat is transferred by a moving fluid (heat rises!), usually water or air
Radiation –
atoms are heated by light
