Conduction - Answer-direct transfer of energy from molecule to molecule via direct molecular collisions What are the best and worst conductors? - Answer-Worst= gases Best= metals Convection - Answer-heat transfer by physical motion; only takes place in fluids and gases. Heat energy is transferred AWAY from the source. Radiation - Answer-transfer of energy by electromagnetic waves. Radiation can travel through a hard vacuum. Ex: energy from sun specific heat - Answer-c, amount of h...
