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.
Penny. Put the ball, duck and penny in water. Only the penny sinks.
The force of inertia keeps water in a bucket when you swing it.
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.
Surface tension allows water to form a large drop on a penny before popping and spilling off.
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.
Supposidly, a bag of water with a penny in it keeps flys away. However, you really don't need the penny and a half filled bag of water will catch some flys.
sit the glass of water on the penny
When you put a penny in water, its density is greater than that of water, so the penny sinks. This is because the weight of the water displaced by the penny is less than the weight of the penny itself.
hold on to it, value keeps increasing
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.
salt water
A penny can hold a significant amount of water due to its surface tension properties. The water molecules adhere to each other and the metal surface of the penny, preventing the water from spilling over the edges. This allows the water to collect and form a convex meniscus on top of the penny.
A penny would sink in a river because a penny is made mostly of zinc, which is heavier than water. Because the penny is heavier than water, it sinks.
food and water
what water does for your body?It keeps us hydrated and keeps you moving and helps the brain and keeps your blood stream flowing and keeps you healthy and strong and it keeps your body alive and your musclse healthy and keeps you from a heat stroak and all the other diseases
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.
Yes because the chemicals in the penny will mix up with the water and the plant sucking the water will kill it.
