The property of a liquid that measure the liquid's resistance to flow is heat of vaporization. surface tension. boiling point. viscosity.
What is a liquid's heat of vaporization? It is the amount of heat needed to vaporize one liter of the liquid at its boiling point. It is the amount of heat needed to melt one gram of the liquid at its freezing point. It is the amount of heat needed to vaporize one gram of the liquid at its boiling point. It is the amount of heat needed to vaporize one kg of the liquid at its boiling point.
