Insulator is a material which don't let heat come through it.
100
Can you see a radiation?
Sometimes you can see the types of radiation. For example you can see a Visible Light.
100
What is conduction?
Conduction is the transfer of energy between matter that is touching.
100
What is convection?
Convection is transfer of energy through the motion of molecules.
100
Can energy be destroyed?
No energy can't be destroyed.
200
What is conductors?
Conductors is materials which let through the heat.
200
What type of radiation is the most dangerous?
The most dangerous type of radiation is Gamma Rays.
200
In which state of mater, conduction will work the best?
For conduction the best state of mater will be solid.
200
Can convection happen in all states of mater?
No it can happen only in liquids and gases.
200
What will transfer heat energy faster water or metal?
Metal will transfer heat energy faster than water.
300
What is the differences between insulator and conductor?
Insulator don't let heat come thought it, but conductor douse.
300
What type of radiation have the smallest amount of energy?
The type of radiation what have the smallest energy is Radio waves.
300
For what the air in the thermos?
The air in the thermos don't let water to change its temperature.
300
Where the heater is more helpful, on the top of the wall or on the bottom?
On the bottom of the wall is more helpful, because it heats the cold air on the bottom, and it becomes hot air and it rises up. And that way it mixes.
300
Where molecules moving faster in water or in metal?
In water, because water is a liquid and metal is a solid. In solids, molecules only vibrate, and in liquids they are moving.
400
For what insulators can be used?
Insulators can be used for warm cloth.
400
Which type of radiation the Sun gives, and it might be dangerous for you?
The type of radiation what the Sun gives and it might be dangerous is Ultraviolet waves.
400
Can conduction happen when there is distance between objects?
No! Conduction can't happen when there is distance between objects.
400
What water will be on top in the pot, hot or cold?
Hot
400
True or false? Kelvin, Celsius and Fahrenheit are all measures of temperature.
It is true.
500
For what conductors can be used?
Conductors can be used to make pots and fry-pans.
500
For what Gamma Rays can be used?
Scientists use Gamma Rays to study black holes.
500
Can conduction conduct temperature from objects with less energy to objects with more energy?
Yes, conduction can conduct temperature from objects with less energy to objects with more energy.
500
With what speed molecules are moving?
It depends on how many energy are in molecules. If there is many energy in molecules they will move fast, if there is small amount of energy they will move slow.
500
Substances that don't conduct heat are known as what?
The substances that don't conduct heat are known as insulators.
