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.

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 happened when the water finally flowed off the penny?
When the water flows off a penny, it forms into drops due to its high surface tension. This is because the cohesive forces between water molecules are stronger than the adhesive forces between water and the penny's surface, leading to the formation of water droplets.
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?
Impurities typically decrease the surface tension of a liquid by disrupting the cohesive forces between the liquid molecules at the surface. This leads to reduced surface tension because the impurity molecules tend to preferentially accumulate at the surface, weakening the intermolecular forces and making it easier to break the surface.
What variables may play a factor in the amount of drops the penny hold?
Variables that may affect the number of drops a penny can hold include the surface tension of the water, the cleanliness of the penny's surface, the temperature of the water, and the angle at which the penny is inserted into the water. Additionally, the presence of any impurities or substances on the penny could also influence the number of drops it can hold.
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?
Water stays on a penny due to its high surface tension. This property of water causes it to form droplets on non-absorbent surfaces like the smooth surface of a penny, instead of spreading out.
What keeps water on a penny?
The surface tension of water keeps it on a penny. Surface tension is the result of intermolecular forces between water molecules that create a "skin" on the water's surface, allowing small objects like a penny to float.
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.
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.
