What takes place when water changes from a liquid to gas?
it evaporates due to change in heat reaching or exceeding it's evaporation point
A physical chaqnge takes place without any changes in molecular compostiotion. Ice is a solid form of water and melts at 0°C and changes to a liquid state. From the liquid state water can change into water vapour by boiling the water at liquid state. At a 100°C water boils and forms into a gas called steam or water vapour.
