A student is melting beeswax to make a candle. The wax starts out at 25◦C and melts at 63◦C.

1. Draw a nano G/R diagram for the period when the wax is heating up but not yet at the melting point. Give
a brief explanation of the energy changes in your diagram.

2. Draw a nano G/R diagram for the period when the wax is at its melting point. Give a brief explanation of
the energy changes in your diagram.

3. Next, the student stops heating the beeswax and lets it cool. Draw a nano G/R diagram for the period when
the wax is cooling down but has not yet solidified (frozen). Give a brief explanation of the energy changes in
your diagram.

4. Draw a nano G/R diagram for the period when the wax has reached its melting point and has started to
solidify (freeze). Give a brief explanation of the energy changes in your diagram.
