Aluminum is one of the metals whose heat conductivity is very high. Quartz is the crystalline solid composed of Si-O bonds. Assume that the same heat flux is incident on the above-mentioned two materials simulataneously. Heat is assumed to be transported mianly by radiation. Which material is much heated? Aluminum? or quartz? Tell me your answer and its reasons. Thank you. |
