What is the role of “loose” electrons in heat conductors?
(A) Loose electrons move quickly away from hot locations, making it impossible for energy to move and making the object a good insulator.
(B) Loose electrons absorb energy, giving materials a high specific heat capacity.
(C) Loose electrons vibrate and emit radiation that carries energy through the material at the speed of light.
(D) Loose electrons transfer energy rapidly through a solid.
Heat loss occurs through windows by the following processes: (1) through the glass panes; (2) through the frame, particularly if it is metal; (3) ventilation around edges; and (4) radiation. (a) For the first three, what is (are) the mechanism(s): conduction, convection, or radiation?(b) Heavy curtains reduce which of these heat losses? Explain in detail.
A bag containing 0 °C ice is much more effective in absorbing energy than one containing the same amount of 0 °C water. (a) How much heat transfer is necessary to raise the temperature of 0.800 kg of water from 0 °C to 30.0 °C ? (b) How much heat transfer is required to first melt 0.800 kg of 0 °C ice and then raise its temperature? (c) Explain how your answer supports the contention that the ice is more effective.
