A piece of wood lying in tu,mj: bcis;7jr9, w k-ydtq 1hh .voh4lp rx(w4 -jjh5oe Sun absorbs more heat than a piece of shiny metal. Yet the wood feels less hot than the metal4j p5-(o.ow4v xlhhjr when you pick it up. Explain.
参考答案:
The thermal conductivity of the wood is about
2000 times less than that of the aluminum.
Thus it takes a long time for energy from the wood to flow into your
hand. Your skin temperature rises very slowly
due to contact with the wood compared to contact with the aluminum, and so the
sensation of heating is much less.
