Energy Transfer: Particles Flashcards
1
Q
Why are saucepans made of metal?
A
Because metal is a good conductor of energy, energy is transferred through it quickly. This is conduction.
2
Q
What 3 ways can energy be transferred by?
A
Conduction, convection and radiation
3
Q
How do particles transfer energy in conduction?
A
They vibrate and collide and transfer the heat
4
Q
What are bad conductors of energy called?
A
Insulators
5
Q
Give an example of an insulator?
A
Wood and many non-metals
6
Q
Can insulators not at all transfer heat?
A
They can transfer heat, but very slowly
7
Q
Are liquids good conductors of energy?
A
No they are very bad conductors
8
Q
Why do gases and liquids not conduct heat/energy well?
A
Because there particles are much more spread out than in solids
