So, he climbed up to the tree, toward the foot of the mountain shout loudly: "help! wolf is coming! " 一天,牧羊人男孩在草放置,看云彩慢慢地渐渐离开,感觉非常乏味,想要做笑话对村庄的其余在山下。 如此,他大声地上升了由树决定,往山呼喊的脚: “帮助! 狼来临! " [translate] athermal mechanical...
BecausePTC heaterelements are self-limiting, theydo not require extra sensors or switches. Instead, the heating element itself acts to limit heat output. As the temperature of the element rises, the current moving through the element is slowed at a proportional rate. In other words, PTC heaters...
According to the professor, what is the purpose of heating an element in a spectroscopic flame test? 托福托福 03 - Spectroscopy 材料音频 去精听 查看全文 题目 L4 123456 A . To cause an element to emit light B . To study an element in combination with other elements...
A kettle element is the part of an electric kettle that actually turns electrical current into heat, thereby heating the water in the kettle. The element is generally located at the bottom of a kettle. Some kettles employ elements that resemble tubes and run through the lower part of the ...

He uses an electric heater and a thermometer, inserted into separate holes in an aluminium block.The following dat a are obtained.mass of aluminium block =2.0 kg power of heating element = 420W time of heating = 95 s initial temperature of block = 19.5 C final temperature of block = ...
MALE PROFESSOR: Well, a kind of spectroscopic library of elements was compiled using flame tests.A known element, uh, say a piece of iron for example, is heated in a pure gas flame.The iron eventually heats to the point that it radiates light.This light is passed through a prism, which...
