What else can I help you with?
Amy has a plastic cup filled to the top with water She uses an eyedropper to add more water and discovers that it takes many drops before the water spills over the top This cohesiveness results from?
the cohesive nature of water molecules, which allows them to stick together and form a strong surface tension. This surface tension keeps the water contained in the cup despite adding more water drop by drop.
Why does water not form on the outside of a cup when you have a hot drink?
Water does not form on the outside of a cup when you have a hot drink because the heat from the drink is transferred to the cup and prevents the air surrounding the cup from reaching its dew point and forming condensation. This is because the cup acts as a barrier, keeping the outer surface temperature above the dew point.
How long does it take to evaporate half a cup of salt water?
The time it takes to evaporate half a cup of salt water depends on various factors such as temperature, humidity, air circulation, and surface area. On average, it could take several hours to a day for half a cup of salt water to fully evaporate.
What makes dish soap bubble?
Dish soap contains surfactants that reduce the surface tension of water, allowing bubbles to form. When agitated or mixed with air, the soap molecules surround the air, trapping it in a thin film and creating bubbles. This effect is further enhanced by the presence of stabilizers and thickeners in the dish soap formula.
What is the lab result of putting 1 cup of water in a mug vs a loaf pan and place in sunny window?
If you place 1 cup of water in a mug and a loaf pan in a sunny window, the water in the mug will likely evaporate faster due to the larger surface area exposed to the sunlight and air compared to the water in the loaf pan. This is because the rate of evaporation is influenced by surface area, temperature, and air circulation.
Why doesn't water spill in a cup?

Why does water form a dome in a cup?
Water forms a dome in a cup due to surface tension, which is the cohesive force between water molecules. This tension causes the molecules at the surface to attract each other more strongly, resulting in a curved, dome-like shape. Additionally, the adhesion between water and the cup's surface can also contribute to this effect, allowing the water to rise slightly above the rim without spilling.
Is a brimming cup of water filled to the top or halfway full?
A brimming cup of water is filled to the top, just at the edge, often with a slight convex surface due to surface tension. It indicates that the cup is full and can hold no more water without spilling.
How a pin can float on the water in a cup?
A pin can float on water due to surface tension. Water molecules at the surface are more attracted to each other than to the air above, allowing the pin to sit on top of the water without sinking. This surface tension supports the weight of the pin, enabling it to float.
If you had a cup of water and put it in a bowl of water what is keeping the water in the cup?
What does this question even mean?If you're asking why some little droplets of water remain in the cup after pouring it, it's basically due to surface tension and the fact that the surface of glass is somewhat hydrophilic.If you've just set the cup upright in the bowl, then it's a little something called gravity.ANSWER IT PLEASEWhen a cup of water, held upright, is dropped on the moon, the air makes the cup fall faster than the water.A.TrueB.False
How does water and nutrients travel up a plant's stem going against the force of gravity and grow themselves for many feet?
It happens through capillary action, which is an effect connected to surface tension in water. If you look at the water in a glass drinking-cup you will see that the water curls up at the edges to form a meniscus. That is caused by surface tension. In a narrow tube the effect is more marked, and in a very narrow tube - a capillary - the water is driven up continuously. That is how plant life is possible, and of course it led on to animal life and eventually to human life.
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 water droplets can be found outer surface of cup?
Your question is imprecise - we do not get the point of what you are asking. Water droplets can be found on the outer surface of a cup if it has just been washed!
Why a cup crack when it is filled with boiling water?
When a cup is filled with boiling water, the heat from the water caused the material of the cup to experience thermal expansion. If the cup is badly made, then different parts of it will expand to different extents and this will create stresses in the material of the cup causing it to crack.
How many paper clips will float in a cup of water?
It will be very depending on the glass size. You may float 100 paper clips on the sink.
Where did the water droplets come from On the cup of ice?
That's condensation—the water vapor in the air around the cup condenses on its surface because it's cold. So it comes from the air around the cup.
