I asked a question earlier about a thermometer in a can containing a substance that is being heated.Temperature remains the same for minutes, then start to rise. Without looking in the can, how does student know whats occurring in the can?I was told a phase change what kind of phase change is it?

Answer 1

Do you know what a phase change is? Ice changing from a solid to a liquid (melting) is a phase change (solid to liquid). water boiling and changing from a liquid to a gas (steam) is a phase change. Either of these phase changes could have caused the behavior you describe.
