Does the amount of soap mixed with water affect how well the water will stay on a penny?
Yes, the amount of soap mixed with water can affect how well the water will stay on a penny. Soap reduces the surface tension of water, causing it to spread out more easily. Too much soap can prevent the water from forming a cohesive layer on the penny, causing it to bead up or slide off.
How do you make a penny float?
One way to make a penny float is by using the surface tension of water. Carefully place the penny on the surface of water in a bowl or cup, making sure it is placed flat. The surface tension of the water will allow the penny to stay afloat.
Why is the pH of soap 9?
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.
What happens when you throw a penny and a piece of wood into a bowl of water?
When you throw a penny and a piece of wood into a bowl of water, the penny sinks because it is denser than water, while the piece of wood floats due to its lower density. The buoyancy of the wood allows it to stay on the surface, while the penny displaces water equal to its volume until it reaches the bottom. This demonstrates the principles of density and buoyancy in a simple experiment.
Does water stay warmer for longer if it has soap in?
Yes, if pure water and soapy water are present at the same temperature (say 70 Celsius) then soapy water takes long time to return to the normal temperature because its Enthalpy (Energy content) is higher than normal water.
What property of water allowes so many drops of water to stay on a penny?
adhesion
Why can you fit more fresh water drops on a nickel then soapy water drops?
Because the hydrogen molecules in water want to stay connected and once you add soap it messes with the bonds and and they don't stay bonded as strongly. Also the mass and density of the water changes when you add soap.
Does water stay on coin or spread out?
Depends soapy water makes the bond between the water particles weaker. So if you add soapy water then it won't last as long
Why does water stay long on a penny?
Water stays on a penny due to surface tension and cohesion forces. These forces cause water molecules to stick together and to the penny, creating a thin film of water that doesn't easily slide off. Additionally, the hydrophobic nature of the copper in the penny repels water to some extent, further helping the water to stay on the surface.
Does the amount of soap mixed with water affect how well the water will stay on a penny?
Yes, the amount of soap mixed with water can affect how well the water will stay on a penny. Soap reduces the surface tension of water, causing it to spread out more easily. Too much soap can prevent the water from forming a cohesive layer on the penny, causing it to bead up or slide off.
Why does water stay on a penny?
Surface tension allows water to form a large drop on a penny before popping and spilling off.
Drops of water or ice crystals become too large to stay suspended in cloud?
condesation
When water vapour condenseit form tiny drops of water that forms clouds when do this droplets come down as rain?
Individual droplets are so small, that they can stay suspended in the air. If the droplets combine into larger drops that are too heavy to stay suspended, they fall as raindrops.
What makes the soap feel soapy?
There is no chemical reaction. Lathering is just air bubbles getting trapped inside the liquid. Soap has a high surface tension, and so if you introduce air bubbles inside it, they tend to stay for a while (unlike water for instance, where the air bubble won't stay for long and will just rise to the surface and fall out). This is also why you can blow soap bubbles (but not water bubbles).

What can you use to write on frosted glass?
to get it to stay, soapy stuff! or oily stuff
