汽化

汽 = 气 + 氵 : The Queen of Hearts (qi) conducts an experiment in the space station's bathroom (Ø4). She attached an empty balloon (气) to a water bottle (氵) and uses a lighter to make the water boil. Subsequently the water becomes water vapor (汽) and fills the balloon, enabling the queen to estimate the vapor volume.
