A student had 50.0 grams of frozen alcohol and placed it in a beaker on a hot plate. The
student noted that for the first two minutes, the temperature of the alcohol in the beaker did
not change. By the end of the two minutes most of the alcohol was in the liquid state. Explain
how this could happen using the concepts of temperature, kinetic energy, and potential
energy.

I can't draw it here but I'm sure there is a heating curve in your text that will show you that the temperature of a frozen material will rise to the melting point of the solid/liquid AND IT WILL STAY AT THAT POINT UNTIL ALL OF THE SOLID AS MELTED. After tjat the termperature of the liquid will start to rise. You can take this information and plug in PE, KE, and the other concepts.
@DrBob222 I have the exact same question but there is no graph. It’s just the question there is nothing to go off of other than what is stated in the question.
