Level 3 unit 1 part1 Listening Matter is made of atoms and molecules Water for example is the H2O molecule This means that a molecule of water has 3 atoms A water molecule has 2 hydrogen atoms and one oxygen atom Substances like sugar have many atoms in their molecules A molecule of sugar has many atoms including carbine hydrogen and oxygen What is H2O The water molecule What is matter made of Atoms and molecules Matter is made of molecules such as the H2O which is the water molecule Matter can be in one of 3 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 How many states of matter are there Three What happens when we heat a substance the molecules move faster and try to take up more space What happens if we cool a liquid to its freezing point It becomes a solid In a solid the molecules move very little Their positions are almost fixed To be fixed means that their positions dont 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 How can we change a solid into a liquid heat it up How can we change a liquid into a solid cool it down 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 substances For water the solid begins to change into a liquid when its temperature rises to above 0 degrees 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 At what temperature does ice begin to melt Above 0 degree Celsius What does the temperature at which a substance begins to melt depend on The substances 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 What happens if we continue to heat a liquid Molecules move even faster Inside a star such as our sun the temperature is very high Everything inside the sun is a gas According to scientists there are over 65 elements inside the sun These include oxygen and iron Over 90 of the sun is hydrogen gas How many elements are inside the sun More than 65 Yesterday there was
