Heat Flow

What causes convection?
Changes in the density of a fluid created by a heat source
The heating of a fluid
Density Changes
The heating of a fluid causing changes in volume
Lesson: Heat Flow
23/47
How is temperature connected to convection?
Higher temperatures make molecules move slower decreasing volume
Higher temperatures add more mass to the fluid
Higher temperatures make molecules move faster increasing volume
Higher temperatures remove mass from the fluid
Lesson: Heat Flow
24/47
How is density connected to convection?
High temperatures increase volume which decrease density allowing the fluid
to rise
High temperatures decrease volume which decrease density allowing the fluid
to rise
High temperatures decrease volume which decrease density allowing the fluid
to sink
Low temperatures increase volume which decrease density allowing the fluid
to rise

Drag the correct step to each part of the convection
process.
Step The fluid is reheated and repeats the
process.
Step A fluid is heated by a heat source
becoming less dense.
Step This denser fluid sinks back toward the
heat source.
Step Unable to rise the fluid travels laterally
losing heat and becoming denser.

Step This less dense fluid rises until it hits a
barrier which stops it.

Steps of Convection
Lesson: Heat Flow
41/47
What is the first step in convection?
The fluid is reheated and repeats the process
A fluid is heated by a heat source becoming less dense
The denser fluid sinks back down toward the heat source
The less dense fluid rises until it hits a barrier which stops it.
Unable to rise, the fluid travels laterally losing heat and becoming denser
Lesson: Heat Flow
42/47
What is the second step in convection?
The fluid is reheated and repeats the process
A fluid is heated by a heat source becoming less dense
The denser fluid sinks back down toward the heat source
The less dense fluid rises until it hits a barrier which stops it.
Unable to rise, the fluid travels laterally losing heat and becoming denser
Lesson: Heat Flow
43/47
What is the third step in convection?
The fluid is reheated and repeats the process
A fluid is heated by a heat source becoming less dense
The denser fluid sinks back down toward the heat source
The less dense fluid rises until it hits a barrier which stops it.
Unable to rise, the fluid travels laterally losing heat and becoming denser
Lesson: Heat Flow
44/47
What is the fourth step in convection?
The fluid is reheated and repeats the process
A fluid is heated by a heat source becoming less dense
The denser fluid sinks back down toward the heat source
The less dense fluid rises until it hits a barrier which stops it.
Unable to rise, the fluid travels laterally losing heat and becoming denser
Lesson: Heat Flow
45/47
What is the fifth step in convection?
The fluid is reheated and repeats the process
A fluid is heated by a heat source becoming less dense
The denser fluid sinks back down toward the heat source
The less dense fluid rises until it hits a barrier which stops it.
Unable to rise, the fluid travels laterally losing heat and becoming denser
