Answer:
There is no short answer.
Explanation:
Particle Theory suggests that all matter is made up of particles and the hotter they get, the more space there is between the particles. In light of this information, we can say that if we want the tea to be stronger, the space between the particles should be smaller, so the temperature that the tea is brewed at should be lower. We can adjust the temperature for brewing strong and weak tea.
I hope this answer helps.
