Insulation
To reduce heat transfer between objects or environments.
What is the function of insulation?
The transfer of heat through direct contact between materials.
What is conduction?
It provides radiant energy that warms Earth’s surface.
How does the sun affect Earth’s temperature?
Enzymes work best at an optimal temperature, usually around 37°C for humans.
How does body temperature affect enzyme activity?
Daniel Fahrenheit developed the Fahrenheit scale in the early 1700s.
Who created the Fahrenheit temperature scale?
They trap air, which is a poor conductor of heat.
Why are air and wool good insulators?
Metals like copper and aluminum.
Which materials are good conductors of heat?
What is an example of heat transfer in nature?
Proteins can denature, causing cells to malfunction or die.
What happens to human cells if the body overheats?
32°F.
What is the freezing point of water in Fahrenheit?
Walls, roofs, and floors.
What part of the house typically needs insulation?
Why do metal objects feel colder than wood at room temperature?
To create buildings and tools that manage heat efficiently.
Why do engineers study thermal energy in design?
Through adaptations like antifreeze proteins or hibernation.
How do some animals survive freezing temperatures?
0°C is freezing, and 100°C is boiling.
How does the Celsius scale define freezing and boiling points of water?
By using vacuum insulation to prevent conduction and convection.
How does a thermos bottle keep liquids hot or cold?
Fast-moving particles collide with slower ones, transferring energy.
How does conduction work at the particle level?
By being nocturnal or having reflective body coverings.
How do desert animals adapt to extreme heat?
The process by which organisms maintain a stable internal temperature.
What is thermoregulation?
Why is the Fahrenheit scale considered somewhat random in its design?
It helps retain indoor heat, reducing energy use.
Why is insulation important in cold climates?
A measure of how well a material conducts heat.
What is thermal conductivity?
It drives wind, storms, and climate systems through uneven heating.
What role does thermal energy play in weather patterns?
It raises body temperature to help fight infections.
Why is fever considered a defense mechanism?
What is unique about the Kelvin scale?
