Why can so many drops of water fit on a penny

Answered By: Bernard Perry Date: created: Dec 06 2021

Because water molecules at the surface of the water puddle attract more to one other than they do to the air molecules above them, they cling together and form a dome shape on the coin.

Surface tension prevents the water molecules from falling out and spilling..

Is water on a penny cohesion or adhesion

Answered By: Brian Turner Date: created: Feb 14 2022

The attraction of water molecules to other substances, like soil or glass, is called adhesion. As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off. Cohesive forces are strong, but not unbreakable.

Why did the non soapy pure water fit more drops than the soapy water

Answered By: Andrew Sanchez Date: created: Dec 21 2021

Observations and results You should find that plain tap water produces a much larger, stable drop of water on top of the penny than the soapy water does. This is because plain tap water has higher surface tension, so the surface is “stronger” and can hold together a larger drop.

How do you break the surface tension of water

Answered By: Julian Allen Date: created: Oct 12 2021

Floating a needle: A carefully placed small needle can be made to float on the surface of water even though it is several times as dense as water. If the surface is agitated to break up the surface tension, then needle will quickly sink.

What are water properties

Answered By: Daniel Parker Date: created: Jun 02 2022

The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling. A water molecule is slightly charged on both ends. This is because oxygen is more electronegative than hydrogen.

What happens if you put a penny in water

Answered By: Gilbert Sanchez Date: created: Dec 01 2021

When you put your dirty pennies in the vinegar and salt, the copper oxide and some of the copper dissolve in the water. That means some copper atoms leave the penny and start floating around in the liquid. But when these copper atoms leave the penny, they leave some of their electrons behind.

Why does pepper float on water

Answered By: Alex Scott Date: created: Nov 28 2021

Pepper is hydrophobic, which means water is not attracted to it. Therefore, unlike salt or sugar pepper will not dissolve in water. The pepper is able to float on the surface because water molecules like to cling to one another. They arrange themselves in a way that creates surface tension on the top of the water.

Does water or vinegar clean a penny better
