Document Summary

Thermodynamics is the study of energy and energy transfer. Heat and work exist only as transfers of energy they cannot be stored. Heat transfer is the transfer of energy due to a difference in temperature. Examples of heat transfer by conduction, convection, and radiation. https://www. e-education. psu. edu/egee102/print/book/export/html/2053. Conduction is a process by which heat is transferred from the hot area of a solid object to the cool area of a solid object by molecule to molecule contact. https://www. e-education. psu. edu/egee102/print/book/export/html/2053. Convection is a process by which heat is transferred from one part of a fluid (liquid or gas) to another by the bulk movement of the fluid itself. Radiation is transfer of heat through electromagnetic waves through space. https://www. e-education. psu. edu/egee102/print/book/export/html/2053. In-class practice: identify the type of home heat loss pictured in images a-j as either: conduction, convection or radiation https://www. e-education. psu. edu/egee102/print/book/export/html/2053. Heat escaping through the roof of a house. A door hanging wide open, letting in cold air. Heat transfer is treated as simple energy transfers.
