The Different Types Of Heat Transfer

There are three main types of heat transfer. They are conduction, convection, and radiation. The first kind (conduction) occurs when two objects of different temperature are placed in direct contact with each other. When this happens, heat energy moves out of the warmer object and into the cooler object. This occurs until both objects are at the same temperature. The figure below illustrates this.



The second type of heat transfer is convection. It occurs when a fluid physically moves into an area of different temperature and then heats this area up, or cools it down, as a result.

The thick covering of fur also does a good job of keeping it warm.




A heat exchanger has the opposite purpose to that of insulation. It is a device used to enable the transfer of heat energy from one place to another, whereas insulation is used to reduce the transfer of heat energy from one place to another. An automobile radiator, shown in the first picture, is an example of a heat exchanger. It is used to remove heat from the engine and transfer it to the atmosphere. This prevents the engine from overheating. Heat exchangers use many fins to increase the rate of heat transfer. Fins increase the rate of heat transfer by increasing the surface area from which heat transfer occurs.

Learning Goals

*Students will understand the concept of heat transfer.
*Students will recognize that differ substances transfer heat at a different rate.

Context for Use

This lab can be modified so it takes an entire class period or ten to fifteen minutes. The equipment needed includes: heat source (hot plate or burner), Styrofoam cup, beaker, thermometer, and metal samples. The students should know what "specific heat" is, although this lab can be used as an introduction to the concept. Basic math/algebra skills are necessary. It is very easily adaptable.

Subject: Chemistry:General Chemistry:Thermodynamics:Heat
Resource Type: Activities:Lab Activity
Grade Level: High School (9-12)

Description and Teaching Materials

*This activity may be modified so students determine the identity of an unknown metal instead of the heat gained by the water.
