1 Chapters 16 Temperature and Heat 1

2 Overview of Chapter 16 Temperature and the Zeroth Law of Thermodynamics Temperature Scales Thermal Expansion Heat and Mechanical Work Specific Heat Conduction, Convection, and Radiation 2

3 16-1 Temperature and the Zeroth Law of Thermodynamics Definition of heat: Heat is the energy transferred between objects because of a temperature difference. Objects are in thermal contact if heat can flow between them! When the transfer of heat between objects in thermal contact ceases, they are in thermal equilibrium. - Have the same temperature 3

4 16-1 Temperature and the Zeroth Law of Thermodynamics The zeroth law of thermodynamics: If object A is in thermal equilibrium with object B Object C is also in thermal equilibrium with object B Objects A and C will be in thermal equilibrium if brought into thermal contact. In short: Temperature is the only factor that determines whether two objects are in thermal equilibrium 4

5 16-1 Temperature and the Zeroth Law of Thermodynamics All have the same Temperature! 5

6 16-2 Temperature Scales The Celsius scale: Water freezes at 0 Celsius. Water boils at 100 Celsius. The Fahrenheit scale: Water freezes at 32 Fahrenheit Water boils at 212 Fahrenheit 6

7 16-2 Temperature Scales Converting between Celsius and Fahrenheit: Converting between Fahrenheit and Celsius : 7

8 16-2 Temperature Scales Kelvin scale is similar to the Celsius scale, except that the Kelvin scale has its zero at absolute zero.! Conversion between a Celsius temperature and a Kelvin temperature: 8

9 16-3 Thermal Expansion Most substances expand when heated; the change in length or volume is typically proportional to the change in temperature.! The proportionality constant is called the coefficient of linear expansion. 9

10 16-3 Thermal Expansion Some typical coefficients of thermal expansion: 10

11 16-3 Thermal Expansion A bimetallic strip consists of two metals of different coefficients of thermal expansion, A and B in the figure. It will bend when heated or cooled. 11

12 16-3 Thermal Expansion The expansion of an area of a flat substance is derived from the linear expansion in both directions: 12

13 16-3 Thermal Expansion The change in volume of a solid is also derived from the linear expansion: For liquids and gases, only the coefficient of volume expansion is defined: 13

14 16-3 Thermal Expansion Some typical coefficients of volume expansion: 14

15 16-4 Heat and Mechanical Work Experimental work has shown that heat is another form of energy. One kilocalorie (kcal) is defined as the amount of heat needed to raise the temperature of 1 kg of water from 14.5 C to 15.5 C. Mechanical equivalent is: 15

16 16-5 Specific Heats Heat capacity of an object is the amount of heat added to it divided by its rise in temperature: Q is positive if ΔT is positive - Heat is added to a system. Q is negative if ΔT is negative 16 - Heat is removed from a system.

17 16-5 Specific Heats Heat capacity of an object depends on its mass. A quantity which is a property only of the material is the specific heat: 17

18 Here are some specific heats of various materials: 16-5 Specific Heats 18

19 16-6 Conduction, Convection, and Radiation Conduction, convection, and radiation are three ways that heat can be exchanged. Conduction is the flow of heat directly through a physical material 19

20 16-6 Conduction, Convection, and Radiation Combining, we find: The constant k is called the thermal conductivity of the rod. 20

21 16-6 Conduction, Convection, and Radiation Substances with high thermal conductivities are good conductors of heat! Those with low thermal conductivities are good insulators 21

22 16-6 Conduction, Convection, and Radiation Convection is the flow of fluid due to a difference in temperatures, such as warm air rising. The fluid carries the heat with it as it moves. 22

23 16-6 Conduction, Convection, and Radiation All objects give off energy in the form of radiation, as electromagnetic waves! - Infrared, visible light, ultraviolet - Unlike conduction and convection, can transport heat through a vacuum. Amount of energy radiated by an object due to its temperature is proportional to: - Surface area - Fourth of temperature I.e. T 4 23

24 16-6 Conduction, Convection, and Radiation Behavior is described by: e is emissivity, and σ is Stefan-Boltzmann constant: 24
