|
What is Convection? (p. 332)
|
Energy is carried away by a heated gas or liquid that expands and rises above cooler, denser liquid.
|
|
|
The flow of a fluid due to heated expansion followed by cooling and contraction.

|
|
|
A device that transfers energy as heat out of an object to lower its temperature.
|
What is a Cooling System? (p. 343)
|
Energy is transfered from one substance to another, leaving the 1st with less energy and thus a lower temperature.
|
|
|
The center of a planetary body, such as Earth.

|
What is a Colloid? (187)
|
