11/1/2009 1 Chapter 10 Thermal Physics Thermal physics is the study of Temperature Heat How these affect matter 10.1 Zeroth Law of Thermodynamics If objects A and B are separately in thermal equilibrium with a third object, C, then A and B are in thermal equilibrium with each other. Allows a definition of temperature

11/1/2009 2 Temperature Two objects in thermal equilibrium with each other are at the same temperature Temperature is the property that determines whether or not an object is in thermal equilibrium with other objects 10.2 Temperature scales Common features: pick two known points and divide the range into some steps (degrees) Harder than you think--You can’t really see temperature, and can’t really feel it with consistency. Fahrenheit scale Excuse: first try Quite messed up: 0 o F and 100 o F don’t quite mean anything, although 100 is roughly the body temperature. Celsius scale Water freezing point: 0 o C Water boiling point: 100 o C

11/1/2009 3 Ice point: 0 o C, 32 o F Boiling (steam) point: 100 o C, 212 o F Celsius degrees are bigger steps than Fahrenheit degrees (therefore Fahrenheit scale has bigger numbers, most of the time) F = 9/5C + 32 Quick check: If C = 0 o C, F = 32 o F If C = 100 o C, F = (9/5) x 100 + 32 = 212 o F Another form of the equation: C = (5/9)(F – 32) 5 9 0 100 32 212 The Kelvin Temperature Scale Motivation: 1. To get people more confused 2. Temperature actually has an absolute 0 In thermal physics, temperature is a measure of the kinetic
