Please find answer in explanation column

Explanation:

Numbering the steps in the correct order to show how ice changes into gas, we have that

1.Ice molecules vibrate in a fixed place.

2. Ice is heated and the molecules speed up

3. The molecules gain enough kinetic energy to leave their solid form.

4.The water becomes liquid and gets hotter.

5. The molecules leave their liquid form and enter the air as a gas.

Ice is the solid form of water  which cannot freely move around in this form  so  it vibrates  about its fixed position.When heated,its molecules acquire energy and its vibration  speeds up  causing it to overcome its  binding forces (that makes it vibrate about a fixed position) and becomes mobile as it leaves its solid form to acquire a liquid state.    With continuous heating, the liquid gets hotter making the molecules vibrate more rapidly, spread out and move freely at high speeds to form Water vapour - The gaseous state of water.

c, liquids evaporate, creating a gas
