Heat Transfer Project By Jacob Shearman

Conduction Example 1 • Situation: Marshmallows on metal sticks are touching hot logs on a fire. • Log is the hotter object and the object losing heat. • Marshmallow is the colder object and the object gaining heat. • This is an example of conduction because the marshmallows are directly touching the log.

Conduction Example 2 • Situation: Heat is flowing inside and out of the house via the window. • On a summer day outside is hotter and losing heat and inside is cooler and gaining heat. • On a winter night outside is cooler and gaining heat and inside is hotter and losing heat. • This is an example of conduction because heat is transferred due to the air touching the window.

Radiation Example 1 • Situation: Sun is radiating down on the earth. • The hotter object and the object that is losing heat is the sun. • The colder object and the object which is gaining heat is the earth. • This is an example of radiation because the earth is being warmed by electromagnetic waves that have traveled through the empty space.

Radiation Example 2 • Situation: A jeep is giving off radiant energy. • The car is the hotter object and is losing heat • The surroundings are the colder objects and are gaining heat. • This is an example of radiation because all objects continually emit radiant energy.

Convection Example 1 • Situation: Land sea breezes. • Day source: Land • Night source: Sea • Fluid: Air • Day fluid motion: Land heats the air, and the warm air rises. • Night fluid motion: Sea heats the air, and the warm air rises.

Convection Example 2 • Situation: Movement of Earth’s plates. • Source: Earth’s outer core • Fluid: Molten rock layers • Fluid motion: Source heats up rock layers which rise and then cool as they reach surface and drop.
