生活中的10个常见科学常识，你了解多少？英文双语对照

科学常识1：水的密度

我们都知道水可以漂浮在油之上，这是因为水的密度大于油的密度。水的密度通常为1克/立方厘米，而油的密度通常为0.9克/立方厘米。

科学常识2：冰的密度

冰是固态的水，但其密度却比液态水小，这也是为什么冰可以浮在水面上的原因。

科学常识3：万有引力

地球上的万有引力加速度大约是9.8米/秒²，这意味着如果你从高处掉下来，你会加速向地面。

科学常识4：色温

在光学中，色温是用来描述光源颜色偏暖还是偏冷的指标，通常以开尔文（K）作为单位。

科学常识5：空气压力

海平面处的标准大气压约为101.3千帕，而气压随海拔的升高呈指数递减。

科学常识6：光合作用

光合作用是植物利用光能将二氧化碳和水转化为能量的过程，释放出氧气。

科学常识7：相变规律

物质在不同温度下会发生凝固、融化、汽化等相变，其温度称为物质的相变点。

科学常识8：生物多样性

生物多样性是指地球上所有生命体的种类和其遗传差异，包括动物、植物、微生物等。

科学常识9：压强

压强是单位面积上受到的压力，通常用帕斯卡（Pa）作为单位。

科学常识10：摩擦力

摩擦力是两个物体相互接触时产生的阻碍它们相对滑动或滚动的力。

Scientific general knowledge 1: The density of water

We know water can float on oil, because the density of water is more than oily density,this is. The density of water is normally1 gram / cubic centimeter, and oily density is normally0.9 grams / cubic centimeter.

Scientific general knowledge 2: Glacial density

Ice is the water of solid state, but its density is smaller than liquid state water however, this also is it why be put on the ice is OK to why be put on the ice float is in the reason on surface.

Scientific general knowledge 3: Gravitation

Tellurian gravitation acceleration is about9.8 meters / second 2, if you fall down from altitude,this is meant, you can be quickened to the ground.

Scientific general knowledge 4: Colour temperature

In optics, colour temperature it is to use descriptive illuminant color to warm or slant cold index, normally withArticle opening Er (K)As the unit.

Scientific general knowledge 5: Air pressure

The standard atmosphere that sea level is in is about101.3 1000 handkerchief, and what atmospheric pressure follows height above sea level is elevatory show an index to decrease successively.

Scientific general knowledge 6: Photosynthesis

Photosynthesis is the plant uses light energy general the process of carbon dioxide and energy of water translate into, release an oxygen.

Scientific general knowledge 7: Change the rule

Material can happen below different temperature caky, melt, the photograph such as vaporization changes, its temperature calls matterChange dot.

Scientific general knowledge 8: Biology diversity

Biology diversityIt is the sort that points to all life style on the earth and its heredity difference, include animal, plant, microbial etc.

Scientific general knowledge 9: Intensity of pressure

Intensity of pressure is the pressure that gets on unit area, use normallyPascal (Pa)As the unit.

Scientific general knowledge 10: Attrition force

The block up that attrition force is the generation when two objects are contacted each other the force that they slide relatively or rolls.
