Heating Curve ( Ice to Steam )

The heating curve of ice shows how the temperature of ice changes as heat is added to it:
Solid phase
The ice remains ice as heat is added, and the temperature increases steadily. The slope of the line depends on the mass of the ice and its specific heat.
Melting phase
The ice melts into liquid water at a constant temperature of 0°C for water. During this phase, the energy added to the ice goes into breaking the hydrogen bonds that keep the water molecules in place as a solid.
Boiling phase
The liquid water boils into a gas at a constant temperature of 100°C for water.
Temperature increase
After the ice has completely melted, the temperature of the liquid water will increase steadily until it reaches 100°C.
The flat parts of the heating curve, where the temperature remains constant, are called phase changes. Different substances have different melting and boiling points, but their heating curves are similar in shape.
