Question

The graph given below represents the change of water from solid state to gaseous state. That means, A represents ice at -10°C. D represents steam at 100°C. I, II, III and IV represent the various phases during the transition.
Answer the following questions based on the given information.

1. Identify the phases which represent change in state from ice to water and water to steam. (1 mark)
2. Identify the phases in which water coexists in two states.(1 mark)
3. Explain the changes taking place in the particles from B to C.(1 mark)
4. Why does phase IV require greater amount of heat than phase II ? (1 mark)
5. what is the physical state at C.(1 mark)​

Answer 2

Answer:

1= phase 2 solid to liquid phase 4 water to steam

2=phase 2 and phase 4
