A spoon was kept in contact with ice cubes for some time. Later, the same spoon was held over the flame of a small candle. The figure shows the observation. What do you infer from the given figure ?


Spoon is an inflammable substance.


Burning of candle is a spontaneous process.


is a product of combustion


Water vapour is a product of combustion


From the figure what we infer is that the spoon which was earlier in contact  with ice cube, on heating gives water vapour  because of vapourisation of water on heating. equilibrium is achieved  firstly on heating cold liquid water then only vapours start appearing , showing combustion reaction is completed.
