Explanation:
The water molecules begins to leave their fixed position and begins to move as the temperature increases.
When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.
- The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
- In the ice, the molecules are locked and fixed in the lattice
- As the temperature increases, the average kinetic energy of the particles rises.
- This makes the structure of the ice to collapse and forms liquids.
- By the virtue of this, they flow and move over one another
- With increasing temperature, the bonds are broken and vapor forms
made up of more than one cell.
Answer:

Explanation:
Given:
- mass of water,

- initial temperature of water,

- final temperature of water,

- specific heat of water,

<u>Now the amount of heat energy required:</u>



Since all of the mechanical energy is being converted into heat, therefore the same amount of mechanical energy is required.
Answer:
distance can describe the total distance moved and displacement shows how far something has moved from its starting position (in a straight line from point a to point b) the object doesn't have to move in a straight line, but that is how displacement is measured
