construct a heating curve for a substance that is heated to 150 deg centigrade. The substance is originally solid at 35 deg c, melts at 75 deg c and boils at 126 dec c

• science -

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
