Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.
What else can I help you with?
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.
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.
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.
What holds more soapy water or pure water on a penny?
Soapy water will hold more on a penny compared to pure water. This is because the surface tension of soapy water is lower than that of pure water, allowing it to spread out more and cover the penny's surface.
What is the difference in drops of water you can fit on a penny if you use soap and regular water?
When you place regular water on a penny, surface tension allows you to fit about 15-20 drops before it overflows. However, when you add soap to the water, the surface tension decreases, allowing more water to spread out rather than bead up. As a result, you can typically fit around 10-15 drops of soapy water on the penny, demonstrating the effect of soap on water's surface properties.
Does the temperature affect number of drops needed for surface tension on a penny?
the chemistry of cohesion
When conducting an experiment of surface tension of water on a penny what is the independent variable?
Temperature.
Effect of impurities on surface tension of liqiud?
yes The presence of impurities either on the surface or dissolved in it, affect surface tension of the liquid. Highly soluble substances increase the surface tension of water, whereas sparingly soluble substances reduce the surface tension of water. The surface tension of a liquid decreases with increase in temperature. The surface tension of a liquid becomes zero at its boiling point and vanishes at critical temperature.
What variables may play a factor in the amount of drops the penny hold?
Several factors can come into play here.The size of the dropsHow fast the liquid is being droppedWhat type of liquid is being usedThe temperature of the liquidThe termperature of the pennyIf the penny was clean or dirtyThe height the drop falls fromAny of these things can have an effect an expansion of the liquid, surface tension, and splash.
How surface tension behaves?
for example, if drops of water are placed on the top of a penny, the surface tension is going to hold the drops on top of the penny. when the penny can hold no more, it will all overflow. make sense?
What is the word for why the water stays on top of the penny?
Surface tension
How does the height affect the ammount a penny can hold?
The height of the water in a container affects the surface tension holding the water in place. If the height is too low, it may not be enough to overcome the adhesive forces of the water molecules, causing the water to spill when adding the penny. If the height is too high, the adhesive forces may be strong enough to hold the water with the penny even without surface tension.
Why does water stay on a penny?
Surface tension allows water to form a large drop on a penny before popping and spilling off.
What keeps water on a penny?
Surface tension keeps water on a penny even when it goes over the surface of the penny and you think it would spill over the edge due to gravity. I believe surface density is accomplished due to the fact that the hydrogen bonds, for that scale, is stronger than the force of gravity. For more information look at the Related Links below.

Drops on a penny?
The surface tension of water allows drops to sit on a penny without overflowing. This is due to the cohesion of water molecules, which causes them to stick together and form a dome shape on the penny. Additionally, the adhesive forces between the water and the penny help to keep the water droplet in place.
How does a penny hold water?
A penny can hold water due to two properties: surface tension and cohesion. Surface tension causes the water molecules to stick together and form a dome-like shape on the penny's surface, while cohesion allows the water molecules to stick to each other and the penny, preventing the water from spilling over.
