2008年5月12日14时28分，汶川发生了8.0级地震，造成了很的多人员的伤亡．通过实验室提供的数据了解到：人的比热容与水相当[C_水=4.2×10³J/（kg•℃）]，求

（1）质量为60kg的一具尸体从体温37℃降至室温25℃（大约需要半天时间）散出热量是多少？

（2）若每千克葡萄糖完全分解释放的热量为1.6×10⁷J．此外，尸体的散热量大约为正常人在相同时间内散热量的60%．根据这些数据估算出一个正常人体内每天必须补充的葡萄糖为多少？

答案

（1）尸体的质量m=60Kg，则尸体半天所散失的热量Q=cm（t-t₀）=4.2×10³J/kg•℃×60Kg×（37℃-25℃）=3.024×10⁶J．　

（2）正常人一天所散失的热量为Q'=

2Q

60%

=

2×3.024×106J

60%

=1.008×10⁷J，则人每天需要补充的葡萄糖为m=

Q′

C葡萄糖

=

1.008×107J

1.6×107J/Kg

=0.63kg=630g．

答：（1）质量为60kg的一具尸体从体温37℃降至室温25℃（大约需要半天时间）散出热量是3.024×10⁶J．

（2）一个正常人体内每天必须补充的葡萄糖为630g．
