If you add 2.0 grams of MgO to water, what will happen to the freezing and boiling points of water?

Yes i think so not 100 percent sure though

Ithink this is what you meant. the temperature at which a liquid begins to boil is called the boiling point. the boiling point of water is 212°f or 100°c.  and at that point will start to turn into steam (gas)

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is
