Bond number
Imagine you are playing with toy boats in a bathtub. You notice that when you blow air on the water, the boats start to move away from each other. This happens because of something called "surface tension". Surface tension is like a force that keeps the water together, like a film on top of the water.
Now imagine you have two boats that are tied together with a rope. You blow air on the water again, and you notice that the boats still move apart, but not as much. This is because the rope is adding some strength to the boats and makes it harder for them to move away from each other.
The bond number is like a measurement of how strong the rope is compared to the surface tension. If the rope is really strong, the bond number is high. If the surface tension is much stronger than the rope, the bond number is low.
Scientists use the bond number to study how different materials interact with each other. This can help them design better materials for things like building bridges, making airplanes, or creating medical devices.
