Thermal insulators and thermal conductors
What is the best thermal insulator?
wood or rubber.
What is radiation?
radiation is a type of energy that can travel through space and sometimes travels in the form of a wave.
True or false? Convection is the energy transfer through touch.
False, that is conduction.
If you were making a spoon would you use a thermal insulator or a thermal conductor?
thermal insulator?
What is the worst thermal insulator?
metals such as silver and copper etc.
what is convection?
It's when warmer parts of a liquid or a gas rise and the cooler parts sink.
True or false? Temperature is a measure of how much thermal energy something has.
False, Temperature measures how hot/cold something is.
If you were making a pot Would you use a thermal insulator or a thermal conductor?
You would use a thermal conductor.
What is the best thermal conductor?
metals such as silver and copper etc.
What is conduction?
The transfer of energy though touch.
True or false? Thermal energy is associated with the random motion of particles at the molecular scale.
True.
What is energy transfer?
It is the process by which energy is relocated from one system to another.
What is the worst thermal conductor?
wood and rubber.
If you boil water what happens?
Convection.
True or false? When heat is added to something its temperature always goes up.
False, the substance could be changing state.
True or false? Energy cannot be created or destroyed.
True.
