Visualize billiard balls shifting really speedy and imparting their kinetic Electricity on to another ball, This really is exactly the same as h2o within the molecular scale. Ice has considerably less heat because the molecules are within a lattice and go quite bit by bit, all through waters transition towards the gasoline stage the molecules have adequate kinetic Electrical power to escape the majority h2o and go away as steam.
