Question

Water can change into ice on cooling and again into water on heating so this is a reversible change, right? Can you tell what can be the reason for the above experiment that why it changed into ice on cooling and water on heating?

Answer 1

Answer:

decreasing the temperature caused the stability of molecule and increasing the temperature caused instability in molecule .

Answer 2

Answer:

When we heat ice, it melts to form liquid water. A change from solid to liquid takes place during the melting of ice. If we cool the water from ice to water, by heating, has been reversed by cooling. Thus, the melting of ice (to form water) is a reversible change
