狂丸研究所，每天涨点新知识

最近天气实在是热得要命，出门在外空调太大拿不动，风扇小巧但要占另一只手，走在外头又变成了一种酷刑。

但最近，狂丸在网上看到有人用手机喇叭成功吹灭了一根蜡烛，非常神奇。

这要是真的，以后夏天出门可就太方便了，一边玩手机一边吹风，舒服。

经过一番搜索，原来，能让手机吹灭蜡烛的是一款叫做Blower（吹风机）的app，图标就是一个风扇和蜡烛，一看就是老blower了。

打开之后能看到界面非常的简单：像模像样的仪表盘搭配写着on/off的开关。

只要点击它，下面的轮盘就会开始加速旋转，发出临场感十足的嗡嗡声。

蜡烛也很配合，应声而熄。

如果搭配上另一个手机……这孩子，或许能拿来变魔术？.gif

除了吹蜡烛，这东西还可以当成一个迷你型号的、专门吹落叶的机器来用。

桌上的橡皮屑再也不会乱跑，都吹成堆儿一起清理掉。

反向改装一下，手机很可能就变成一个吸尘器了。

但众所周知，手机不是等等党梦里的那块原价显卡，一般里面是没有风扇的。

那这吹蜡烛的风，到底是从哪里来的呢？

还记得轮盘启动时手机发出的拟真嗡嗡声吗？我们都知道，声音由振动产生，但它本身是不能推动空气形成风的。

空气中的粒子只会像下图中显示的那样，在某个范围内波动，最终还会回到原本的位置。

这款app便是通过控制手机驱动扬声器，从而带动扬声器处的空气波动，从小孔附近一进一出形成力扑灭蜡烛。

app启动时将扬声器靠近火苗，就可以清楚地看到部分火焰呈现一个被吸入的趋势。

但虽然吸入和吐出时空气的量是相同的，可蜡烛并不会在空气被吸入时被吸力熄灭，因为空气被吸入时是来自吸取源的各个方向，大家没有心往一处想，拧成一股绳，没啥力度。

所以只有被喷出时比较集中，这才能保证蜡烛被熄灭。

视频中的老哥还用吸尘器和棉球做了个实验来验证这一点：棉球放在进风处纹丝不动。

而在出风口处，一下子就被吹跑了。

自此，既然掌握了声音才是这个app的神奇之处，那么如果找对相应震动频率的声音，其实不用这个app也能达到吹灭蜡烛的效果。

同样应用声音方面原理的还有那个号称手机进水神器的软件Sonic Ⓥ。

打开之后是这个样子的，只要按一下中间那个水滴按钮，调大音量，就能排出部分水分。

调到某些频率时，手指贴近扬声器真的能感觉到有气流吹拂。

确实有网友反应好用，把濒临溺死的手机抢救了回来。

不过，要是当场开不开机，还是拿去手机店修吧……

同理，那些号称有着给手机「物理清灰」能力的app和视频，其实都是用不同频率的声音带动空气来达到所谓的清灰目的。

至于清理能力是否真的有效，那就说不好了。

目前，那款叫做Blower的app在苹果商店售价12块人民币，感兴趣的朋友可以买来试试，不过要是吹蜡烛的话，我干嘛不用嘴呢？

阮赖炒13840754701 ______[答案] 【实验探究】通过实验分析可知:切开蜡烛,取出打火石,用砂纸打磨,打火石呈银白色,该金属一定不是铜,因为铜是紫红色;取少量打磨后的打火石于试管中,滴加稀盐酸,有无色气体产生,溶液为无色,该金属一定不是铁,而是镁,因为氯化...

关终奚4009蜡烛燃烧时生二氧化碳和水,为什么没把火焰烧灭 -
阮赖炒13840754701 ______ 蜡烛燃烧生成的二氧化碳和水量不多,在与周围环境中大量空气比较起来,量实在很小. 并且因为蜡烛燃烧时,周围的空气因为受热不均,会强烈对流,燃烧产生的废气会与新鲜空气不断进行气体交换,因此,火焰不会被烧灭.

关终奚4009蜡烛在水上燃烧为什么不会熄灭 -
阮赖炒13840754701 ______ 汗!因为蜡烛不溶于水.... 当空气充足 燃料充足 温度达到 当然还是会燃烧的 在水上并没有改变燃烧的三大必备条件

关终奚4009整蛊玩具吹不灭的蜡烛的原理是什么 -
阮赖炒13840754701 ______ 我饺着应该是含有镁粉,能在吹出去的二氧化碳中燃烧.吹这种蜡烛的时候不是会冒小火星么,挺符合镁粉燃烧的现象的.然后再接触到氧气的时候小火星就能再次点燃蜡烛,就吹不灭啦~

关终奚4009...而且看上去和普通的蜡烛一模一样,到底是什么玄机能让蜡烛持续燃烧?请你一起参与探究.【查阅资料】普通蜡烛由石蜡和蜡烛芯制成的,而吹不灭的蜡烛... -
阮赖炒13840754701 ______[答案] 【探究与反思】:从题干信息对打火石的成分主要是合金可知:打火石是混合物,利用燃烧的条件可知:灯芯金属不燃烧是因为蜡蒸气起到了隔绝空气的作用,要想使其熄灭:可控制燃烧的条件完成,如隔绝氧气或剪除灯芯或用...

关终奚4009为什么蜡烛在水里不会灭
阮赖炒13840754701 ______ 因为蜡烛密度小,浮在水面上.

关终奚4009在农村老人去世后,在棺材上会放一盏蜡烛,为什么一定不能让它熄灭? -
阮赖炒13840754701 ______ 因为那个蜡烛是用来给老人去世后引路的,如果蜡烛熄灭,那么老人将失去方向

关终奚4009蜡烛燃烧后为什么不会消失?而化成蜡油,,好奇怪啊.. -
阮赖炒13840754701 ______ 蜡烛燃烧后产生了热量,水,二氧化碳,因为有能量的损失,所以最终融化的蜡油重新凝固的体积及质量总比燃烧前的小

关终奚40091771年英国科学家普利斯特利将点燃的蜡烛与绿色植物一起放在一个密闭的玻璃罩内,蜡烛不容易熄灭.今天我们对这一现象最合理的解释是( ) -
阮赖炒13840754701 ______[选项] A. 植物可以更新空气 B. 蜡烛燃烧所需要的物质来自绿色植物 C. 绿色植物在烛光下能制造有机物 D. 绿色植物在光照下进行光合作用释放氧气

关终奚4009五年级科学:蜡烛的燃烧原理是什么?不用谢太复杂,一句话就够了. 帮帮忙啦.....快...... -
阮赖炒13840754701 ______ 蜡烛是可燃物,火焰达到了蜡烛的着火点,同时蜡烛与空气(也就是氧气)接触了. 物体燃烧的条件有三个.同时满足这三个条件、物体就会燃烧. 即:可燃物;达到可燃物着火点;可燃物与空气(或氧气)接触.
