Question

#16 formula sheet calculator periodic table heating curve of water temperature °c 100 75 50 25 0 -25 -50 a b c d e 400 800 1200 1600 2000 2400 2800 3200 heat added (kj) what does segment b represent? a the heat of fusion b the heat of sublimation c the heat of vaporization

Explanation:

Segment B on the heating - curve of water is at 0°C where the temperature remains constant as heat is added. This is the phase - change from solid (ice) to liquid (water), and the heat required for this phase - change is called the heat of fusion.

Answer:

A. the heat of fusion
