A piece of metal is heated until it becomes red-hot, it is then quickly transferred into a beaker containing boiling water. What effect will this have on the boiling water?
the boiling water rises slightly
the boiling point rises sharply
the rate of vaporisation of the boiling water increases
the boiling point first rises and then falls
neither the boiling point nor the rate of vaporisation increases
