Q
what is conduction
A
vibrations are passed on between particles in a solid
they can spread electricity and/or heat easily
2
Q
what is convection
A
when part of the fluid is warmer than the rest rises from the bottom then sinks back down
3
Q
what is radiation
A
radiation is the only way energy can be transferred in a vacuum
4
Q
what does low thermal conductivity mean
A
energy is not transferred through them very easily by heating
5
Q
what happens when you increase the thickness of an object
A
the rate of energy transfer is reduced
