3 Mechanisms for Heat Transfer

Ch 4, Lesson B, Page 14 - 3 Mechanisms for Heat Transfer

• In the next few pages, we will use our cup of hot tea to guide our discussion of the three mechanisms for heat transfer.
• As long as the tea is hotter than its surroundings, the system is not at thermal equilibrium and heat will continue to be transferred from the tea to the surroundings.
• Here we list the three mechanisms for heat transfer and the key equation that we will use to calculate the heat transfer rate due to each mechanism.
• The total heat transfer rate is the SUM of the three rates.
• In the next few pages, we will look at each mechanism more closely.
