生活中有关物理化学知识的常识？

物理：用拳头砸墙会痛（力的作用是相互的）；夏天打开冰箱有雾气（外界空气中的水气遇冷凝结）；冬天双手用力搓动会暖和（摩擦起热）；

化学：鸡蛋放进醋里，蛋壳会变没（醋和蛋壳反应）；做包子馒头的面团放进苏打，做出来的包子很松软（苏打加热会生成二氧化碳，从而在面团里面鼓起小泡泡）；汽油可以用来洗去衣服上面的笔迹（有机溶剂互溶）

生活中和密度有关的物理现象？

这种现象有登山一公里海拔高度，空气密度由浓厚变稀薄后感觉呼吸或耳朵不适，飞机飞行时起飞降落过程也是。 水在冬天变成冰后密度变小可以浮在水面上。

冰会浮在水面上的原因是：水在4℃以上，仍然是遵循热胀冷缩规律的，从4℃以下，即4℃到0℃间才发生反常膨胀。水在4℃时，体积最小，密度最大。因而冰的密度略小于水的密度。所以可以浮在水面上。

物理小常识？

1小小称砣压千斤——根据杠杆平衡原理，如果动力臂是阻力臂的几分之一则动力就是阻力的几倍。

 2、有时自来水管在邻近的水龙头放水时，偶尔发生阵阵的响声。这是由于水从水龙头冲出时引起水管共振的缘故.

  3、对着电视画面拍照，应关闭照相机闪光灯和室内照明灯，这样照出的照片画面更清晰。因为闪光灯和照明灯在电视屏上的反射光会干扰电视画面的透射光.

鸵鸟的生活常识？

鸵鸟是一种非常有趣的动物，让我们一起了解一些关于它的生活常识吧！鸵鸟是一种草食性动物，主要以草、种子、叶子和根茎为食。它们会在清晨和傍晚觅食，而在白天炎热的时候则会躲在阴凉处休息。鸵鸟是一种孤独的动物，它们通常独自行动或与同伴一起生活。尽管它们是群居动物，但在寻找食物和休息的时候，它们更喜欢单独行动。鸵鸟是一种跑得非常快的动物，它们可以达到每小时70公里的速度。不过它们的奔跑主要是在短距离内，长距离奔跑则会消耗大量的能量。鸵鸟是一种不会飞的鸟类，但它们却能够跳跃高达2.5米的高度。因此，它们建立了地下巢穴来繁殖和休息。鸵鸟是一种非常聪明的动物，它们可以记住水源和食物来源的位置，并在需要时返回。它们也会使用策略来保护自己免受捕食者的攻击。鸵鸟是一种非常耐旱的动物，它们可以在没有水的情况下生活几个星期。它们通过控制呼吸和体温来适应干燥的环境。鸵鸟是一种非常有防御性的动物，它们可以使用它们的强壮腿部来保护自己免受捕食者的攻击。它们的体型和速度也让它们在面对威胁时更有优势。总之，鸵鸟是一种适应力非常强的动物，它们的生活习性使它们能够在荒野中生存和繁衍。

基本的生活常识？

Is the common sense of physico-chemical knowledge concerned in the life?

Physics: Break a wall with fist the meeting is painful (the action of force is each other) ; Summer opens freezer to have fog (the hydrosphere in outside air encounters condensation to written guarantee) ; Winter both hands exerts oneself to do sth. rub moves meeting thaw (the heat since attrition) ;

Chemical: The egg is put into vinegar, chorion can change not (vinegar and chorion reaction) ; The dough that makes steamed bread of steamed stuffed bun is put into soda, the steamed stuffed bun that makes is very loose (soda heats can generate carbon dioxide, rouse small hubble-bubble inside dough thereby) ; Benzine can use the hand above scour off dress (dissolve of organic dissolvent each other)

Does the life counteract the physical phenomenon that density concerns?

This kind of phenomenon has mountain-climbing one kilometer height above sea level, air density by grumous breath of the feeling after becoming rare or ear are unwell, when the airlines flies, take off descend the process also is. It is OK that water turns the density after ice into decrescent in the winter float is on surface.

The reason that puts meeting float on the ice to go up in surface is: Water is in 4 ℃ above, remain abide by heat to bilge cold shrink of the rule, from 4 ℃ the following, namely 4 ℃ produce abnormality to expand to the ability between 0 ℃ . Water is when 4 ℃ , volume is the minorrest, density is the biggest. The density that puts on the ice consequently is less than the density of water slightly. So can float is on surface.
