L3-U2-P1-1 Listening : States of Matter
States of Matter
Matter is made of atoms and molecules.√
Water, for example, is the H2O molecule.√
This means that a molecule of water have 3 atoms.√
A water molecule has two hydrogen atoms and one oxygen atom.√
Substances like sugar have many atoms in their molecules.√
A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.√
听选What is Matter made of?-Matter is made of atoms and molecules.
听选What is H2O? - It's the water molecule.
听选How many hydrogen atom in water molecule？-A water molecule has two hydrogen atoms and one oxygen atom.

排序 ①Matter is made of atoms and molecules.②Water, for example, is the H2O molecule.③This means that a molecule of water have 3 atoms.④A water molecule has two hydrogen atoms and one oxygen atom.√
Matter is made of molecules, such as H2O, which is the water molecule.√
Matter can be one of three states, solid, liquid or gas.
Water and ice are the same substance, but they are in different states.√
These states depend on the temperature of the molecules.√
When we heat a substance, the molecules move faster and try to take up more space.√
When we cool a substance, the molecules move more slowly.√
When we cool a substance to its freezing point, it becomes a solid.√
听选How many states of matter are there? -There are three states of matter.
听选What happens if we cool a substance to its freezing point?-When we cool a substance to its freezing point, it becomes a solid.
听选What does matter depend on?-These states depend on the temperature of the molecules.
填空Water and ice are the same substance,but they are in different states.
填空These states depend on the temperature of the molecules.
In a solid, the molecules move very little.√
Their positions are almost fixed.√
To be fixed means that their positions don’t change.√
If we heat the molecules, they move faster and away from each other.√
The solid begins to melt, like ice cream on a hot day.√
听选How can we change a liquid into a solid?- cool it
听选In which state are the molecules almost fixed? - In a solid, the molecules move very little.

Matter is made of atoms and molecules.
A molecule of sugar has many atoms, including carbon, hydrogen and oxygen.
At a certain temperature, a solid begins to change into a liquid.√
The temperature at which a solid changes into a liquid depends on the substance.√
For water, the solid begins to change into a liquid when its temperature rises to about 0 degree Celsius.√
For some substances, such as steel, the temperature at which it becomes a liquid is much higher.√
Steel often melts at around 1370 degrees Celsius.√
听选What does the melting temperature depend on?-The temperature at which a solid changes into a liquid depends on the substance.
听选What does the temperature add begin to melt depend on?-The temperature at which a solid changes into a liquid depends on the substance.
填空At a certain temperature, a solid begins to change into a liquid.
填空 Ice begins to change into a liquid when its temperature rises to above 0 degrees.
填空Steel often melts at around 1370 degrees Celsius.√
If we continue to heat a liquid, the molecules move even faster.√
At a certain temperature, the liquid begins to change into a gas.√
For water, the liquid begins to change into a gas at 100 degrees Celsius.√
That is the boiling point of water.√
听选What is boiling point of the water？ -100 degrees Celsius.
听选At what temperature does water boil？-water boil temperature is 100 degrees Celsius.
听选What happens if we continue to heat a liquid?- If we continue to heat a liquid, the molecules move even faster.
填空If we continue to heat a liquid, the molecules move even faster.
填空At a certain temperature, the liquid begins to change into a gas.
Inside a star, such as our Sun, the temperature is very high.√

Over 90 percent of the Sun is hydrogen gas.√
