Answer:
Excited State
Explanation:
It's when electrons absorb energy and move to a higher level.
Energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.
<h3>Heat energy</h3>
Heat energy is a form of energy transferred from one body to another due to a temperature difference between the bodies.
Heat energy is also known as thermal energy.
In heat transfer, heat is transferred from a body at higher temperature to a body at lower temperature.
In the heat transfer between the heated aluminium and the water, the solid aluminium is at a higher temperature than the water, hence, heat energy is transferred from the aluminium to water.
Therefore heat energy is transferred from the Al (solid) to water and the temperature of the water increases while the temperature of the Al (solid) decreases.
