<u>Answer:</u>
<em>The energy to turn the ice into water:</em>
- The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
- Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
- Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
- After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.
Upwelling
Explanation:
The rise of deeper water to the surface is called upwelling.
Upwelling is a term used in oceanography to describe the rise of cold and denser water to the surface.
- This occurs usually along the short where wave action is very prevalent.
- Surface wave pushes away warm water.
- Then deeper nutrient-rich cold water rises due to low density and volume of water on top.
- This nutrient rich water supports biological activities because they are rich.
- Wind along the coast can also force surface water down.
