Heat & Temp
This was designed because our bodies cannot sense exact temperatures, and some temperatures are dangerous.
What is a thermometer?
All matter is made up of these.
What are tiny particles?
The transfer of heat energy between substances through direct contact.
What is conduction?
The colour of material that most easily absorbs and transfers heat.
What is black?
Fridge, freezer, air conditioning system
When heat is removed from a sample of matter, it will do this (except water!).
What is contract?
All particles have this between them.
What are spaces?
The transfer of heat energy when fluids move from place to place in a current due to different densities.
What is convection?
This is what happens to the temperature of a surface if it is covered by a glass dome.
What is increase?
Materials designed to easily transfer heat throughout their particles are classified as ________.
What are conductors?
The temperature scale where "0" corresponds to the temperature at which particles stop moving.
What is the Kelvin scale?
This is what happens to the motion of particles when heat is added to them.
What is increase?
The transfer of heat energy without using matter.
What is radiation?
The colour and texture of a roof that would reflect a lot of heat and keep the inside of a building cool.
A type of thermometer used to measure temperature inside a thermostat - it changes shape when heated or cooled, resulting in either completing or breaking the circuit that turns on your furnace.
What is a bimetallic strip?
This is the average body temperature in humans.
What is 37 degrees Celcius?
This state of matter has no definite volume and its particles move quickly.
What is a gas?
The type of heat transfer that allows heat to escape a thermos with a vacuum (no matter at all) between the walls.
What is radiation?
List two natural sources that can directly transfer heat or be converted directly into heat energy.
The type of thermometer you would use to measure the temperature of something too far away to actually touch.
Explain why liquid inside a thermometer moves up and down when the temperature changes.
Warmer = expands and fills tube more
Colder = contracts and fills tube less
Using the particle theory, explain what is happening when you boil a liquid.
As more heat is added to the liquid, the particles move more and more, eventually spreading out to become a gas.
The type of waves that are used to transfer heat by radiation (infrared waves are an example of this).
What are electromagnetic waves?
What is wind or hydro?
The reason why we put furnace vents on the floor of our homes is...
What is convection?
