Modes of Heat Transfer
- Conduction is heat transfer in which particles of the body do not leave their positions.
- Conduction occurs in solids and in mercury.
- In metals, conduction mainly takes place through free electrons.
Heat Conduction, Isothermal Surfaces, and Temperature Gradient
- In a conductor, heat flows from the hot end to the cold end.
- In variable state, the temperature of each cross-section of a rod increases with time.
- In steady state, the temperature of each section remains constant with time.
Thermal Conductivity and Thermal Resistance
- Coefficient of thermal conductivity measures how much heat flows through unit area per unit time under unit temperature gradient in steady state.
- A large value of K means a good heat conductor.
- A small value of K means a poor conductor or a good insulator.
Heat Flow Through Composite Slabs
- When slabs are joined in series, the same heat flow passes through each slab in steady state.
- For slabs in series, interface temperature is found by equating the heat flow through both slabs.
- For equal lengths in series, interface temperature becomes a weighted average of end temperatures.
Key Concepts
Central concept: Heat transfer and thermal conduction in different media and bodies, including radiation, convection, thermal conductivity, black body radiation, and cooling laws
