标题合金和纯金属的熔点
时间Tue Feb 28 12:00:13 2006
Alloys are mixtures of pure metals in either the liquid or solid phase
which of the following is usually true of alloys?
1 the melting/freezing point of an alloy will be lower than that of
either of the component metals because the new bonds are stronger
2 the melting/freezing point of an alloy will be lower than that of
either of the component metals because the new bonds are weaker
3 the melting/freezing point of an alloy will be greater than that of
either of the component metals because the new bonds are stronger
4 the melting/freezing point of an alloy will be greater than that of
either of the component metals because the new bonds are weaker
5 none of the above
这一题各位觉得是那一个呢
合金应该是要看用什麽元素才能和纯金属比较吧
我是认为不一定 请问一下各位的高见
谢谢
