total speed of atoms + What the atoms are made of +how many molecules
4
Q
heat transfers from…. to ….
A
high temperature to low temperature (source to sink)
5
Q
rate depends on…
A
temperature difference
6
Q
a Thermometer tells us…

how fast the atoms in the mercury are moving
7
Q
conduction only occur if
A
the source must be in contact with the sink
8
Q
