What happened to the water in the basin when you placed a drop of water on it
This sounds like an observation question. So when you placed a drop of water on the water in the basin, what did you observe; ;i.e., what did you see it do?

When you place a drop of water on a basin, several things can happen to the water. To understand what happens, let's discuss the properties of water and the forces acting on it.
1. Surface Tension: Water has a property called surface tension, which is the cohesive force between water molecules at the surface. It creates a "skin" on the water's surface, allowing it to hold together.
2. Gravity: Gravity is a force that pulls objects downwards. It acts on the water drop to try to pull it downwards.
Now, when you place a drop of water on a basin, the following can happen:
1. Spreading: The drop may spread out on the surface of the basin. This happens because of the cohesive nature of water molecules. The surface tension pulls the water molecules together, causing the drop to spread out and form a thin film.
2. Beading: The drop may form a round bead on the surface. This occurs when the surface tension is strong enough to resist gravity. The cohesive forces within the drop overpower gravity, causing the water to hold together in a spherical shape. This is often observed when the drop is relatively small.
The specific outcome depends on various factors, such as the surface tension of the water and the surface of the basin, temperature, and the size of the water drop.
To experiment and observe what happens when a drop of water is placed on a basin, you can:
1. Find a basin or a shallow container.
2. Using a dropper or pipette, carefully place a drop of water on the surface of the basin.
3. Observe the behavior of the water drop and see if it spreads out or forms a bead.
4. You can also try different water droplet sizes and temperatures to see how they affect the outcome.
By performing these experiments, you can gain a better understanding of the properties of water and the interplay of forces that determine what happens to the water on the basin's surface.
