Why does the needle float when it is dropped in water parallelaly and why it sinks when dropped perpendicularly?
When the needle is dropped parallel to the water's surface, it creates surface tension and stays afloat due to the weight distribution. However, when dropped perpendicularly, the needle displaces more water, causing the weight to overcome the surface tension, thus sinking.
How do soapy water drops stay on a penny?
When soapy water is dropped on a penny, the surface tension of the water allows it to form a dome-like shape rather than immediately spreading out. The soap molecules reduce the surface tension of the water, allowing it to adhere to the penny and form a cohesive drop.
What shape is water?
Water takes the shape of whatever it surrounds but on the surface it takes on a level shape
What will happen to a solid object made from matter with a greater density than water when it is dropped into water?
The answer depends on the shape of the object. Ships, made from steel, which is denser than water, do float!
What is the verb in this sentence wind and water shape earth's surface?
shape
Why small water drops are spherical in shape?
Small water drops are spherical in shape due to surface tension. Surface tension is a property of liquids that causes them to minimize their surface area, resulting in a spherical shape for small droplets as it is the shape that has the lowest surface area. This is why small water drops tend to form perfect spherical shapes.
Is food color is dropped into water to give it color a chemical change?
no, a physical change
What happens when wax is dropped into boiling water?
When wax is dropped into boiling water, it melts and forms a layer on the surface of the water. The melted wax will eventually cool and harden, creating a thin layer on top of the water.
Why does water become spherical when thrown in air?
Water tends to form a spherical shape when thrown in the air due to surface tension. Surface tension causes the water molecules to stick together and minimize the surface area, forming a spherical shape, which has the least surface area for a given volume.
What is the scientific explanation behind the formation of the drop shape in water?
The drop shape in water is formed due to surface tension, which is the cohesive force between water molecules at the surface. This force causes the water molecules to stick together and form a spherical shape, as it minimizes the surface area and maximizes the volume of the drop.
What is the shape of a drop of oil placed in the surface of water?
A drop of oil placed on the surface of water will typically form a near-perfect circle due to surface tension forces that minimize the surface area of the liquid.
Why does liquid water take the shape of a sphere?
Liquid water tends to form spherical droplets due to surface tension, which minimizes the surface area of the water droplet. This results in a spherical shape, as it has the smallest surface area for a given volume of water.
