L3-U2-P1-1 Listening : States of Matter 物质的状态
Matter is made of atoms and molecules.
物质由原子和分子组成。
Water, for example, is the H2O molecule.
例如，水就是H2O分子。
This means that a molecule of water has 3 atoms.
这意味着一个水分子有3个原子。
A water molecule has two hydrogen atoms and one oxygen atom.
一个水分子有两个氢原子和一个氧原子。
Substances like sugar have many atoms in their molecules.
像糖这样的物质，其分子中有许多原子。
A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.
糖分子有许多原子，包括碳、氢和氧。
Matter is made of molecules, such as H2O, which is the water molecule.
物质由分子组成，比如H2O，也就是水分子。
Matter can be one of three states, solid, liquid or gas.
物质有三种状态：固态、液态或气态。
Water and ice are the same substance, but they are in different states.
水和冰是同一种物质，但它们处于不同的状态。
These states depend on the temperature of the molecules.
这些状态取决于分子的温度。
When we heat a substance, the molecules move faster and try to take up more space.
当我们加热一种物质时，分子运动得更快，并试图占据更多的空间。
When we cool a substance, the molecules move more slowly.
当我们冷却一种物质时，分子运动得更慢。
When we cool a substance to its freezing point, it becomes a solid.
当我们把一种物质冷却到它的冰点时，它就变成了固体。
In a solid, the molecules move very little.
在固体中，分子很少运动。
Their positions are almost fixed.
它们的位置几乎是固定的。
To be fixed means that their positions don’t change.
固定意味着它们的位置不变。
If we heat the molecules, they move faster and away from each other.
如果我们加热分子，它们会运动得更快，并彼此远离。
The solid begins to melt, like ice cream on a hot day.
固体开始融化，就像在炎热的日子里冰淇淋融化一样。
At a certain temperature, a solid begins to change into a liquid.
在一定的温度下，固体开始变成液体。
The temperature at which a solid changes into a liquid depends on the substance.
固体变成液体的温度取决于这种物质。
For water, the solid begins to change into a liquid when its temperature rises to about 0 degree Celsius.
对于水，当它的温度上升到约0摄氏度时，固体开始变成液体。
For some substances, such as steel, the temperature at which it becomes a liquid is much higher.
对于某些物质，如钢，它变成液体的温度要高得多。
Steel often melts at around 1370 degrees Celsius.
钢通常在1370摄氏度左右熔化。
If we continue to heat a liquid, the molecules move even faster.
如果我们继续加热液体，分子会运动得更快。
At a certain temperature, the liquid begins to change into a gas.
在一定的温度下，液体开始变成气体。
For water, the liquid begins to change into a gas at 100 degrees Celsius.
对于水，当它的温度达到100摄氏度时，液体开始变成气体。
That is the boiling point of water.
这就是水的沸点。
Inside a star, such as our Sun, the temperature is very high.
在恒星内部，比如我们的太阳，温度非常高。
Everything inside the Sun is a gas.
太阳内部的一切都是气体。
According to scientists, there are over 65 elements inside the Sun.
根据科学家的说法，太阳内部有超过65种元素。
These include oxygen and iron.
这些元素包括氧和铁。
Over 90 percent of the Sun is hydrogen gas.
太阳中超过90%是氢气。
