---|---|---|---|
HEAT (or THERMAL ENERGY)
Temperature is a measure of the amount of ___________
|
What is CONDUCTION
This is a picture of the heat transfer___________ (IMAGE A)
|
37 degrees CELSIUS
What is the ideal body temperature for a human?
|
COTTON
Which of these substances makes the best insulator?
A) Copper B) Sand C) Cotton D) Water |
What is a MERCURY thermometer
This type of thermometer can read high temperatures, and is used in laboratories.
|
What is CONVECTION
This is a picture of the heat transfer _____________
(IMAGE B) |
What is HEAT STROKE
This is the condition of dangerously high body temperatures due to the sun's heat.
|
VENTILATION
Which word describes the movement of fresh air to replace stale air?
A) Convection B) Ventilation C) Radiation D) Thermo-regulation |
What is A) Wax melting (conduction, not expansion)
Which of these demos did NOT show thermal expansion:
A) Wax at the end of a heated rod melting B) A balloon shrinking in a freezer C) Bimetallic strip bending when heated D) Alcohol in a thermometer rising |
Dark / Rough / Dull
More heat would be absorbed by materials that are
DARK/LIGHT SMOOTH/ROUGH SHINY/DULL |
SWEATING
This body function helps to cool us through evaporation.
|
Hot, dry, windy, large SA
Which four scenarios increase evaporation rate?
Hot/ cold air Dry / humid air Small/large surface area Windy / still air |
What is a MAXIMUM-MINIMUM thermometer.
What type of thermometer is in this IMAGE (B)
|
What is RADIATION
This heat transfer does not require a substance to travel through.
|
Radiation and convection
In this picture (IMAGE D) which TWO types of heat transfer are penguins preventing for those in the middle?
|
ELEPHANT flapping ears - it is replacing the warm air around its ears with fresh air, promoting radiation.
Which of these methods of thermo-regulation do NOT use evaporation?
A) Elephant flapping ears B) Dog panting over its tongue C) Human sweating D) Kangaroo licking its forearms |
What is FASTER, LOWER DENSITY, RISING
Increase in temperature results in
Faster/slower particle movement, higher/lower density, fluids rising/falling |
What is an INSULATOR
Materials that prevent heat transfer are called this.
|
Any 3 of: constricts blood vessels, slows blood flow, hair stands up to trap air, blood stops flowing to extremities, shivering, no sweat.
Name three things the body does to maintain heat.
|
HEAT STROKE and CONDUCTION
What is wrong with the person in this IMAGE E and which form of heat transfer is being used to help?
A) hypothermia B) fever C) heat stroke D) conduction E) convection F) radiation |
