Question

4. Write about solid-liquid interconversion in
brief.​

Answer 1

Answer:

Matter can change from one form to other form i.e from solids to liquids to gases. The phenomenon of the change of matter from one state to another and back to original state is known as interconversion of the sates of matter. Matter can be changed from one state to another by changing temperature or pressure.

Answer 2

Answer:

At 0°C water is solid and is ice.

when heat is transferred this heats breaks down the strong intermolecular forces of the solid ice and this is converted into 0°C water. When further more heat is transferred to this 0°C then this water is converted to 100°C water and then this water starts boiling and converts into 100°C. and vice versa for the opposite processes.
