Question

How does a cube of ice transform itself into liquid water?

• A. Ice transforms itself into liquid water by releasing heat
• B. Ice transforms itself into liquid water by absorbing heat
• C. Ice transforms itself into liquid water by neither absorbing nor releasing heat
• D. Ice transforms itself into liquid water by both absorbing and releasing heat

Answer 1

The correct option is B

Ice transforms itself into liquid water by absorbing heat

Ice being a solid comprise of very closely packed molecules which possess less kinetic energy. Our target is to convert it into the liquid state in which particles are comparatively at a greater distance and will have higher kinetic energy. So, heat energy has to be supplied to ice so that the forces of attraction between the particles break up and kinetic energy increases.
