How to Formulate an Effective Research Hypothesis
State the problem that you are trying to solve. Make sure that the hypothesis clearly defines the topic and the focus of the experiment.
Try to write the hypothesis as an if-then statement. ...
Define the variables.
Explanation:
-Are the most used in daily life and basic human needs
(such as oxygen,nitrogen,carbon, etc)
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.
