f2 chapter 5的，请用英文回答谢谢030

Answer 1

K will have a higher temperature than J, as tea is considered as an impurity. Impurity will increase the boiling point of a liquid. The boiling point of water is 100C, which means tea water will have a boiling point higher than 100C. Tea water can reach a higher temperature than water without boiling.
加油 :)))))

Answer 2

K is higher than temperature than J(1m). It's because impurities can change the flavor, smell and boiling point(1m).J hasn't any impurities.(1m) Hence K higher temperature than J because the impurities increase the boiling point of K

刚好我也是初二，而且嗯科学成绩勉强还好，我为你做解释一下是指Point一分.因此如果这道题是三分的话，我觉得是可以拿满三分，当然呃要看你的老师是怎么改的。
