1 CHARLIE HAFFEY NORWOOD PUBLIC SCHOOLS Heat & Temperature

2 What Is Heat? A form of energy Transfers among particles By means of particle Kinetic Energy

3 Temperature Measures average Kinetic Energy Of particles in an object Temperature ∝ Kinetic Energy

4 Temperature Scales Celsius Scale (1742) AKA Centigrade 100 divisions Pretty darn clever

5 Celsius Scale 0oC0oC Water freezes/melts 100 o C Water boils 0oC0oC100 o C

6 Absolute Zero Theoretical Temperature No particle Kinetic Energy No Heat

7 Absolute Zero 1 liter of air at -1 o C  1/273 liter decrease in volume -273 o C  273/273 decrease in volume

8 -273 o C100 o C0oC0oC

9 Kelvin Scale AKA Absolute Scale Absolute Zero = 0 K (notice no degree symbol)

10 -273 o C100 o C0oC0oC 0 K373 K273 K

11 Fahrenheit Scale 1714 Based on 100 o F body temp 32 o F MP 212 o F BP 180 divisions between MP and BP Completely Wacky

12 -273 o C100 o C0oC0oC 0 K373 K273 K -460 o F212 o F32 o F
