AOS 100 Homework #2 1) Suppose you go to Camp Randall Stadium to watch he Badgers on a cold November Saturday and you can choose a wooden bleacher seat or a metal one. Does one have a lower temperature than the other? Why or why not? Which one would be more comfortable? Explain your answer with reference to conductivity. Both metal and wood seats have same temperature. Although metals are better conductors of heat, it doesn’t necessarily mean that one should have lower temperature than other one; it is hard to judge the temperature of metal object by touch. However, wooden seat would feel more comfortable than metal one because metal seat, for example an Iron 80.0 Wm - 1o C -1 , will conduct the heat of one’s body away faster and more efficiently compare to wooden one that has 0.08 Wm -1o C -1 . 2) Object A and Object B are placed next to one another in a laboratory enclosure. Object A emits 100 units of radioactive energy every second and yet experiences a steady increase in temperature. What can be concluded about the amount of radiation emitted by Object B? Explain your reasoning. Under these circumstances, what must be happening to the
