Year 6 matter and energy (u5)Online version Revision of matter and energy by GIBBS SARAH MICHELLE A B C D E F G H I K L M N O P Q R S T U V W X Y Z Empieza por A All the matter in the universe is formed of these particles Empieza por B At 100ºC water ................. Empieza por C This gas is very bad for our planet. It is produced when we burn fuels and it is a "greenhouse" gas (it contributes to the greenhouse effect) Empieza por D Separation method used to separate liquids of different densities Empieza por E Separation method used to separate a mixture when one of the components is dissolved in the other Empieza por F Separation method used to separate solid particles from a liquid or gas Empieza por G When matter is in this state, the atoms are moving quickly in every direction Empieza por H A mixture in which the components are combined evenly and we can't distinguish them Empieza por I If a change cannot be undone it is an ................................ change Empieza por K The unit of measurement for mass Empieza por L The fastest form of energy in the universe! (it travels at 300 000 km per second!) Empieza por M In a mixture in which one of the components is a metal we can use a ............. to separate the components Empieza por N Burning this fuel produces pollution but it is cleaner than burning wood or petrol Empieza por O 21% of the atmosphere is formed of this gas Empieza por P An object has this type of energy when it is at rest (not moving) Contiene la Q When matter is in this state, the atoms are close together but they move more than in a solid Empieza por R When light rays bounce off of a completely smooth surface, a clear .................... is produced Empieza por S When water boils and becomes a gas Empieza por T When all the particles in an object have the same temperature it is called ..................... ..................... Contiene la U The chemical reaction when a material reacts with oxygen and burns Empieza por V Liquid water doesn't have a fixed shape but it has a fixed ........................ Empieza por W We can use a container of ...................... to calculate the volume of an object with an irregular shape Contiene la X When a material reacts with the oxygen in the air Empieza por Y The fungus that ferments bread. (It produces carbon dioxide which makes the bread rise) Contiene la Z At 0ºC water .....................
