幫忙翻譯英文的化學題目 順便幫我解答..我滿意的話就給20點

What does it mean to say that the melting point of a pure substance is a characteristic property of the substance?

我只能翻譯到這裡..我們說一個純物質的熔點是他的特性是什麼意思..

但是這樣應該不完整吧..也不太懂題目要問什麼

what is meant by a mixed melting-point determination?

如何去定義一個混何物的熔點? (是這樣翻議嗎...)

答案就麻煩了 謝謝

    Mixed melting point determination involves both compounds being mechanically mixed and pressed into intimate contact with in the sample.

    If one had two samples with the same m.p. a mixed melting point that was lower and broader than the umixed consituants would demonstrate that they were different compounds.

    何謂融點是一個純物質的特性?

    因為每個一個純物質都有其特定的融點 沸點

    也就這個物質所具有的特徵

    可以藉由融點的測定

    當作辨認某一個純物質的條件之一
