A
KE + PE
3
Q
thermal conduction =
A
a process of energy transfer where energy is transferred through the passing on of vibrational motion from one particle to another.
4
Q
what is convection
A
a process of energy transfer by means of convection currents of a fluid (liquid or gas), due to a difference in density.
