  1. 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
