• water is melting
• the sublimation of water

Why does the graph have two flat lines at "b" and "d"?

• Those are times when we took the water off the hot plate
• Those are phase changes where temperature doesn't change while adding heat
• The line is flat because the water is all in the solid or gas phase
• The line is flat because temperature increases the most at those locations
