急急急！！！！！！！！！！！！请大虾们指教指教！！关于电水壶的
通过已知条件，可以通过公式Q吸=Cm（t末-t初）求出水吸收的热量Q吸=3.15×100000mJ,电水壶在10min内所提供的热量为Q放=Q=Pt=600P,在电路图中应该有电水壶的功率和容积，有容积才能算出质量（因为是满壶，所以可以用总容积与水的密度的乘积可以得质量），然后用Q吸/Q放就可以得到热效率.
Educating people as the education is the life and soul, is the essential requirement of education and the value pursuit. Educating people as the education, education should pay attention not only to the development, but also the long-term development, more attention should be paid to the all-round development of people; should pay attention not only to be with people, educating people, but must pay attention to the object -- the country and the people, serve the country, serve the people, and continuously meet the state and people need. "Depending on the people, to people, service people " as the basic starting point, to respect students, love students, student services, shaping the students love, harmonious spiri

电热水壶是通过水壶底部的发热管或电热底盘通电后加热，热量直接被水吸收。
加热管加热的电热水壶加热面积比较少，加热不均匀所以要费电，所以效率在90%左右.
底盘加热的电热水壶加热面积大加热均匀，所以要省电,效率也比加热管加热的电热水壶效率高,要接近或达到95%以上。
在同样的电功率下，用电磁炉烧水比用电水壶烧水快得多，这是由于电磁炉是利用涡流效应来实现对于水壶的加热，而电水壶则是利用传统的电阻性质的电-热转换效应来为水壶加热，两者的工作原理完全不同，电水壶通电后需要一个较长的预热时间才能达到最高的加热温度，而电磁炉可以在通电后立刻就达到最高加热温度，因此在同样功率下加热同样容量的水，电磁炉比电水壶快得多。但是电水壶特别是小容量的电水壶，具有使用快捷方便的突出优点，如果您在冬季烧水仅仅用于饮用，则电水壶显然优于电磁炉。
800、1000、1200瓦大概是这么几个。
效率一般小于1，0.6到0.9之间
1.5升的是1350W 1.8升的是1500W

不要着急，慢慢来，越着急越不行，要稳住，沉住气，事情才能做好。如此着急，说话更应该简洁。而你为什么而急？也得说个清楚呀。现这样急不择言，别人怎么能知道其中的原因呢？不知道什么事让你这么急？急急急，你想回答什么问题？我真不知道你要提问什么问题。什么事你倒是说呀，这急急的，也帮不...
