this is a time/temperature plot
the line slopes up from 35 to 75
while the solid warms up
the line levels off at 75
while the solid melts
phase change
the line slopes up from 75 to 126
while the liquid warms up
the line levels off at 126
while the liquid boils
phase change
the line slopes up from 126 to 150
while the gas warms up
