1.
Why do metals conduct heat well?
They are dense
They have free electrons
They have strong magnetism
They have high c
2.
Conduction through a slab is proportional to
thickness2
independent of thickness
its thickness
1/thickness
3.
Which cannot transfer energy through a vacuum?
Conduction
Radiation
Both
Neither
4.
If the area is doubled and thickness is doubled, the conduction rate
doubles
halves
is unchanged
quadruples
5.
Trapped air is a good insulator because
air is a poor conductor and the trapped air limits convection
air has free electrons
it radiates well
air is dense
