which statement is not correct
energy is released when a liquid changes into a solid
particles move faster in the gaseous state than in the liquid state
the carbon atoms in gaseous methane are further apart than those in solid diamond

The apparatus shown is set up. After 20 minutes a white rimg of ammonium chloride is seen at position Y. Which statement aout the molecules of ammonia and hydrogen chloride is correct?
molecules in ammonia have a larger Mr than molecules of hydrogen chloride and so they move more slowly
molecules in ammonia have a larger Mr than molecules of hydogen chloride and so they move more quickly
molecules in ammonia have a smaller Mr than molecules of hydogen chloride and so they move more slowly
molecules in ammonia have a smaller Mr than molecules of hydogen chloride and so they move more quickly

melting
neutralisation
the diagram shows how the molecules in the exhaust gases diffuse into the air. which statement describe what happens to these molecules next?
