Does a substance have to be cold to freeze?
Tell students that the temperature at which a substance freezes is called the freezing point. The freezing point of water is 0 °C (32 °F). Corn oil and isopropyl alcohol have lower freezing points than water. This means that they need to be cooled to lower temperatures to make them freeze.
How cold is ice in the freezer?

Why you shouldn’t freeze milk?
Yes, milk can last for several months in the freezer, but for the best quality, we advise consuming it within the first month. After that point, milk will begin to separate and turn grainy.
